Buy underpriced items at thrift stores, estate sales, and garage sales for $1-$20, then resell for $20-$300+ on eBay, Poshmark, and Mercari. Experienced flippers earn $1K-$8K/month with consistent sourcing.
Thrift flipping is buying underpriced second-hand goods and reselling them online. The pitch is that a $4 jacket becomes a $60 sale, which is a fifteen-fold return, and that anyone with a phone and a car can do it.
The individual flips are real. The business is something else. Two numbers decide whether it works, and neither of them appears in most guides: the net you keep per sale after the marketplace fee, the postage and the packaging, and the share of your listings that sell in a given month. Multiply those together and divide by the hours you spent, and you get the actual hourly rate. For a large number of people who try this, that number is below their local minimum wage, and they only find out after they have filled a spare room.
This guide works through both numbers with published fee schedules and published postage rates, then covers the sourcing hierarchy, the categories that still function, the legal exposure most guides skip, and the specific circumstances in which reselling is a bad idea.
The Fee Stack, From the Platforms' Own Pages
Marketplace fees are quoted as a single percentage. They are never a single percentage.
eBay, United States
eBay's published US selling fees page sets out a final value fee that is a percentage plus a per-order fee. The per-order fee is $0.30 for orders of $10.00 or less and $0.40 for orders over $10.00.
The headline rates, from the same page:
- Most categories, including the bulk of Clothing, Shoes and Accessories: 13.6% on the total amount of the sale up to $7,500 per item, then 2.35% above that.
- Books and Magazines, Movies and TV, Music: 15.3%. Books are eBay's most expensive ordinary category, which matters enormously to anyone told that books are the beginner-friendly entry point.
- Women's Bags and Handbags: 15% if the sale is $2,000 or less.
- Jewellery and Watches: 15% up to $5,000.
- Coins and Paper Money, sports and non-sport trading cards, collectible card games: 13.25%.
- Men's and Women's Athletic Shoes: 8% if the total is $150 or more, with no per-order fee, and free to list if the starting price is $150 or more. Below $150 the rate reverts to 13.6%.
The single most commonly misunderstood line on that page is what the percentage applies to. eBay states that the total amount of the sale includes the item price, any handling charges, any shipping costs collected from the buyer, sales tax, and any other applicable fees. You pay a commission on the postage your buyer paid and on the sales tax the platform collected on the state's behalf.
eBay's own worked example on that page makes the effect visible: a $400 phone with free shipping, plus 6% sales tax, gives a total amount of the sale of $424. The final value fee is 13.6% of $424 plus $0.40, which is $58.06, plus a $0.35 insertion fee. The seller keeps $341.59 before paying for the postage they promised.
Three further charges are worth knowing before your first bad month:
- Dispute fee: $20.00 for each dispute where you are found responsible, for example a chargeback.
- International fee: 1.65% of the total sale if the buyer's delivery or registered address is outside the US and you are not using eBay International Shipping.
- Performance surcharges. If your account is rated Below Standard on the 20th of the month, eBay charges an additional 6% on the following month's final value fees, rising to 7% after four or more consecutive months. Separately, if your rate of "item not as described" return requests is rated Very High, eBay charges an additional 5% on final value fees in the affected categories, rising to 6% after four consecutive months.
That last one is the trap specific to thrift flipping. Second-hand goods generate condition disputes at a far higher rate than new goods do, and eBay's response is to raise your commission by a fifth.
Insertion fees are 250 free listings per month, then $0.35 per listing, charged per listing and per category, and non-refundable if the item does not sell.
eBay, United Kingdom
The UK position is completely different and is widely misreported.
Since 1 October 2024, eBay's UK fee page states that UK-based private sellers pay no final value fees and no regulatory operating fee, with 300 free listings a month and 35p per listing beyond that. The cost was moved to the buyer: eBay's Buyer Protection fee page states the buyer pays £0.10 flat per item, plus 7% of the item price up to £20, plus 4% of any portion from £20 to £300, plus 2% of any portion from £300 to £4,000, with nothing above £4,000. On a £20 listing the buyer sees £21.50 before postage.
Here is the part that matters to anyone reading a flipping guide: if you buy goods in order to resell them at a profit, you are not a private seller. HMRC's own guidance is blunt about it. "If you buy or make goods to sell at a profit, you're likely to be trading." eBay's business seller fees are a separate schedule, and on that schedule you pay:
- A per-order fee of £0.30 for orders of £10.00 or less, £0.40 above that.
- Clothes, Shoes and Accessories: 11.9%. Women's Bags and Handbags 12.9% up to £800. Men's and Women's Trainers 7% where the item price is £100 or more, otherwise 11.9%.
- Books, Comics and Magazines: 9.9%. Computers, Tablets and Networking 9.9%. Cameras and Photography 9.9%, with several sub-categories at 6.9%.
- Antiques 10.9%, Collectables 10.9%, Crafts 12.9%, Business, Office and Industrial 12.5%.
- A regulatory operating fee of 0.35% on the total amount of the sale.
- Listing fees of 30p per additional fixed-price listing with no shop, or a shop subscription at £27, £77 or £437 a month for Basic, Featured and Anchor.
- Dispute fee £16.80 including VAT (£14 excluding VAT). International fee where the delivery address is outside the UK. All fees on eBay's business seller schedule are exclusive of VAT; 20% VAT is added on top (ebay.co.uk business seller fees, page last updated 4 August 2026).
So the "eBay is free in the UK now" headline, which is true, is not true for you. A UK flipper who registers as a private seller to avoid the business fee schedule is misdeclaring their status, and is also depriving their buyers of the statutory rights covered further down this page.
Mercari
Mercari's fee page is unusually clear. Since 6 January 2025:
- Seller pays a 10% selling fee on the item price plus buyer-paid shipping.
- Buyer pays a 3.6% Buyer Protection fee on the item price plus buyer-paid shipping.
- There is no separate seller payment processing fee on listings created or updated after that date. The old 2.9% plus $0.50 arrangement was retired.
- Direct deposit cash-out is free, with a $2 fee on a failed deposit. Instant Pay is $3 per transfer, capped at $600 a month.
Ten per cent flat with no per-order fee makes Mercari materially cheaper than eBay on low-value items, which is why low-value hard goods migrate there.
Poshmark
Poshmark's fee structure is quoted consistently across a large number of third-party fee calculators and reseller tools as a flat $2.95 on sales under $15, and 20% on sales of $15 or more, with no listing fee. This audit could not retrieve Poshmark's own support page to confirm it: the support site is JavaScript-rendered and returned no readable content to any fetch method tried. Treat the 20% figure as well-corroborated but not primary-verified, and check Poshmark's current fee page before pricing anything.
If the 20% figure is right, the arithmetic is stark: a $50 Poshmark sale returns $40 to the seller before any packaging cost, against roughly $43 on eBay before postage. Poshmark's compensation is that the buyer pays a flat postage charge, so heavy items are not penalised the way they are on eBay.
Poshmark's flat buyer postage rate for packages up to 5 lb is quoted by different reseller publications in 2026 as $6.49, $7.67, $7.97 and $8.45. Those cannot all be current. This audit could not resolve the disagreement against a primary source, so no figure from that range should be relied on for pricing.
Facebook Marketplace
Local pickup sales arranged off-platform carry no fee. For shipped orders processed through Facebook checkout, the sources disagree: several 2026 fee guides state 5% per shipment with a minimum of $0.40 for shipments of $8.00 or less, while others state 10% with a $0.80 minimum. Meta's own help page is behind a login wall and returned no content to any retrieval method attempted here. This audit could not confirm which figure is current. Given a factor-of-two disagreement on a fee, check Meta's own page before you build a business on it.
What is not in dispute is the structural difference: Facebook Marketplace's value to a flipper is local, cash, collected-in-person sales of items too heavy or bulky to post. On those, the fee is zero and the postage is zero. That is the entire reason furniture and appliances flip there and nowhere else.
Depop, Vinted, Whatnot
All three block automated retrieval of their fee pages. This audit did not verify their current rates and therefore quotes none. Depop and Vinted have both restructured seller fees onto buyers in recent years in at least some markets, so any figure you find in an older guide is likely wrong. Check each platform's own page.
Postage: The Cost That Decides Which Items Are Worth Listing
Retail postage in the US is much higher than most guides assume, and platform-discounted labels are much lower. Both matter, because the retail rate is what you pay if you ever post something outside a marketplace label.
USPS Ground Advantage, retail prices, from the USPS published price notice:
- Up to 8 oz: $7.90 in zone 1, rising to $9.45 in zone 8.
- 12 oz to 1 lb: $9.55 to $12.90.
- 2 lb: $10.80 to $19.05.
- 3 lb: $11.30 to $22.40.
USPS Media Mail, retail, which applies to books, printed music, sound recordings and some other media, and to nothing else:
- 1 lb $4.39, 2 lb $5.13, 3 lb $5.86, 5 lb $7.34, 10 lb $11.02.
Platform label rates, from Mercari's published 2026 rate table, which is the clearest public schedule of what a marketplace-discounted label actually costs:
- USPS Ground Advantage: $4.91 at 0.25 lb, $5.66 at 0.5 lb, $7.48 at 1 lb, $12.83 at 2 lb, $14.97 at 5 lb, $20.32 at 10 lb.
- UPS Ground Saver: a flat $7.97 from 0.25 lb through 5 lb.
- Mercari notes that from 7 May 2026 its USPS Ground Advantage and Priority Mail label rates reflect USPS's fuel surcharge.
Now apply this. A folded cotton t-shirt in a poly mailer is comfortably under half a pound, so the label is roughly $5 to $6. A fleece or a pair of jeans is around a pound, so roughly $7.50. A pair of boots in a box is two to three pounds, so $13 to $15. These garment weights are estimates, not sourced figures: weigh your own, because a heavy winter coat can be three pounds on its own and will wipe out the margin on a $25 sale.
Two consequences follow immediately.
First, there is a hard floor under what is worth listing. On eBay at 13.6% plus $0.40, an item priced at $15 with free postage returns $12.56 after commission; take off a $6 label and $0.40 of packaging and you have $6.16 before you count the cost of the item, the petrol, or the twenty minutes you spent photographing it. Price it at $12 instead and you keep $3.57. Items that sell for under about $15 posted are not a business; they are a hobby with a delivery obligation.
Second, weight is a category filter, not a detail. The reason experienced sellers gravitate to jewellery, small electronics accessories, sewing patterns, camera lenses and trading cards is not aesthetic. It is that a $60 item weighing four ounces has a $5 label, and a $60 item weighing four pounds has a $14 to $22 label. Same revenue, radically different business.
And returns are asymmetric. Under eBay's Money Back Guarantee policy, where a buyer opens an "item not as described" case, the seller is responsible for return shipping. On a remorse return, the listing determines who pays. So a disputed $40 sale can cost you the outbound label, the return label, and the item.
Sell-Through Rate: The Number That Kills Large Piles
Sell-through rate is the share of your listed inventory that sells in a period. If you have 200 active listings and 8 of them sell this month, your monthly sell-through is 4%.
This is the number that determines whether "list more" is advice or a trap.
You will see the claim, in many guides and in older versions of this page, that each active listing generates something like $15 to $25 a month in revenue, so 300 listings guarantees a few thousand dollars a month. That claim is untestable and should be distrusted. It is a single aggregate ratio pulled from unstated data, it makes no distinction between a $9 paperback and a $300 lens, and it implies a linear relationship that does not hold: the marginal listing you add is by definition worse than your best listing, because you sourced your best items first.
The honest version is arithmetic you do yourself, and it has three inputs.
- S: your monthly sell-through, as a decimal.
- N: your active listing count.
- P: your average net profit per sale, after platform fee, label, packaging and cost of goods.
Monthly profit is S × N × P. That is the entire model.
Suppose you list 200 items, your monthly sell-through is 4%, and your average net after everything is $12. That is 8 sales and $96 a month. To reach $1,000 a month at those inputs you need roughly 2,080 active listings, which at a realistic listing rate is a different life, not a side hustle.
Change the inputs and the picture changes completely. At 200 listings, 8% monthly sell-through and $30 average net, the same portfolio produces $480 a month from 16 sales. The listing count did not move. What moved was item selection.
This is the central finding of the whole exercise: sell-through and average net per sale are worth more than listing volume, and they are the two things volume advice tells you to ignore.
A few practical implications:
- Track it. Every month, record active listings at the start, and sales during the month. Divide. If you are not measuring S, you are not running a business, you are accumulating objects.
- Dead stock is not neutral, it is negative. An item that has not sold in twelve months has consumed shelf space, a share of your insertion fees if you exceed the free allowance, and the time you spent listing it. On eBay US, Good 'Til Cancelled listings renew monthly and are charged an insertion fee on each renewal once your 250 free listings are used.
- Set a disposal rule before you need one. Something like: anything unsold at 120 days gets repriced once; anything unsold at 240 days gets bundled, donated back, or binned. The sunk cost is already sunk. The storage cost is not.
- Sell-through varies enormously by category and is not a property of you. Common women's fast fashion has very low sell-through because supply is effectively infinite. A specific model of discontinued kitchen mixer has high sell-through because supply is finite and demand is searchable.
Realistic sell-through figures are not published by the platforms in any form this audit could verify. eBay's Terapeak research tool computes sell-through from an individual seller's own search, which is the correct way to get the number for your category. Any guide quoting a universal sell-through rate is guessing. Compute yours.
The Sourcing Hierarchy
Sourcing tiers differ on four axes: price per item, time per item, competition, and how much you can inspect before you commit. They are listed here roughly from most expensive and safest to cheapest and riskiest.
1. Charity shop and thrift store floor
The retail floor of a Goodwill, Salvation Army, British Heart Foundation or independent charity shop. Items are individually priced, sorted, usually washed, and displayed. In most US metropolitan areas a floor-priced garment is several dollars; in the UK a charity shop garment is commonly a few pounds. This audit found no reliable published average floor price, and prices vary by chain and by region, so no figure is quoted here.
- Advantage: you can inspect, try things on, test electricals at some stores, and buy exactly what you want.
- Disadvantage: the price already reflects that staff have sorted for value. Larger chains route recognisable brands to online arms or to auction, so the residual value on the floor is thinner every year.
- Realistic use: best for beginners learning what sells, and for anyone whose time is worth more than the price differential.
2. Outlet stores and the bins
Goodwill's outlet stores, known universally as "the bins", sell by weight from large open containers. Pricing is set regionally and varies more than most guides admit. Three published examples, all from the operating Goodwill regions themselves:
- Goodwill of Colorado, effective 1 January 2026: clothing, shoes, purses and household wares $1.99 per pound; plates, cups, bowls, pots, pans and utensils 79 cents per pound; linen 49 cents per pound; books, DVDs, CDs and records 69 cents each; furniture and heavy items at flat rates of $8, $12 or $15 by weight band.
- Evergreen Goodwill, effective 1 September 2024: electronics, housewares, sporting goods and toys $1.49 per pound; accessories, linens, shoes and textiles $2.29 per pound.
- Goodwill of Silicon Valley: glassware and dishware 49 cents per pound; books 75 cents per pound; electronics $1.29 per pound; housewares, textiles, shoes and accessories $2.99 per pound; CDs, VHS, DVDs and records $1.00 each; video games $3.00 each.
A doubling of the per-pound rate between regions is not a rounding difference. Check the specific outlet's published pricing before you drive there.
What the per-pound price means in practice depends on garment weight, and the weights below are estimates from ordinary experience, not sourced figures: a cotton t-shirt is roughly 0.3 to 0.5 lb, a pair of jeans 1 to 1.5 lb, a fleece around 1 lb, a leather jacket 3 lb or more. At $2.29 per pound, a t-shirt costs about a dollar and a leather jacket about seven. Weigh a few of your own garments before budgeting.
The honest downsides of the bins:
- It is physical work in poor conditions. Bins are dusty, items are unsorted and unwashed, and everything you touch has been touched by everyone before you. Gloves are standard. People with back problems, dust allergies or limited mobility should treat this tier as closed.
- You cannot test anything. Electricals go home untested. Assume a meaningful failure rate.
- Sales are final. Outlets do not take returns.
- Competition is organised. Regular resellers know the rotation schedule and will be at the table when the fresh bins come out.
- Volume forces a listing bottleneck. The whole appeal is buying fifty items for forty dollars. The constraint is that fifty items is fifteen to twenty hours of photographing, measuring, writing and listing. Buying is fast and free; listing is the actual job. Most people who quit thrift flipping quit with a garage full of unlisted stock.
3. Garage sales, yard sales and car boot sales
Individually priced, cash, negotiable, and completely unsorted for value. Which is the point, because the seller is not a professional.
- Arrive early for selection, late for price. Sellers who do not want to carry things back inside will take almost anything at the end.
- Buy in lots. "What would you take for that whole box?" is the single most useful sentence in this tier.
- Weather-dependent, season-dependent, and geographically clustered. Expect to spend as much on driving as on stock in a bad week.
- In the UK, car boot sales are the direct equivalent, typically with a pitch fee for sellers and an entry fee for early buyers.
4. Estate sales
Estate sales are professionally run liquidations of a whole household. That professionalism cuts both ways.
Estate sale companies commonly charge the homeowner a commission of 30% to 50% of gross sales, with 35% to 40% cited as the typical range. This figure comes from trade and industry sources rather than a regulator or a published survey this audit could verify directly, so treat the range as an industry consensus rather than a hard statistic. The relevance to you is that a company taking 35% has a strong incentive to price knowledgeably, look things up, and hold firm on day one.
That leads to the standard tactics:
- Day one is for things you must not miss and are willing to pay near-retail for.
- The final day is usually half price or better, and is where the volume buying happens.
- Whole-lot offers at the end are where the real money is. A company that must clear a house by Sunday evening will sell you everything left in a room for a flat sum rather than pay to have it removed.
- Ask what did not make it to the floor. Companies routinely have things they judged not worth pricing.
Estate sales are also where you most need to know the categories in the legal section below, because household clearances produce cots, upholstered furniture, old electricals and children's products in quantity.
5. Auctions
Live and online auction houses sell estate and consignment goods in lots. The economics differ from every other tier in three ways.
- The buyer's premium. Auction houses add a percentage to the hammer price, and it is charged to you, the buyer. Rates vary widely by house and are published in each house's terms and conditions. This audit did not verify a representative current rate and does not quote one: read the specific auctioneer's terms before bidding, because a premium plus sales tax plus an online-bidding platform surcharge can add a substantial fraction to the hammer price.
- Removal deadlines. Won lots typically must be collected within a short window, often a day or two, or you incur storage charges or forfeit the lot. This is the mechanism by which people accidentally buy a van's worth of goods and no van.
- Box lots. Uninspected mixed lots are the highest-variance purchase available to a flipper. They are also where the folder of first-day covers with the valuable stamp lives. Treat them as lottery tickets bought with the portion of your capital you can afford to lose.
6. Liquidation pallets, storage-unit auctions and returns lots
The bottom of the hierarchy, and the tier that most reliably takes money from beginners.
Pallets of retailer customer returns are sold by weight or by manifest. The manifest states retail value, which is not a price you will ever achieve, and the mix is dominated by items returned because they were broken. Storage-unit auctions are bought sight-mostly-unseen and frequently contain personal effects with no resale value that you are nonetheless obliged to dispose of.
The specific failure mode is that these tiers convert cash into volume, and volume is the thing you already have too much of. If your bottleneck is listing hours (and it will be) buying a pallet makes your business worse, not better. Anyone considering this tier on borrowed money should not.
7. Free
Kerbside collections, Freecycle and equivalents, "free" listings on Facebook Marketplace, and the end of car boot sales. Zero cost of goods, so any sale is pure margin against your time. Overwhelmingly furniture and bulky household items, which is to say local-sale-only items. Worth a route on collection night in an affluent area if you have a vehicle and can lift.
What Still Works, and What Stopped Working
The categories that survive share a set of properties. An item is a good flip when it:
- Has a searchable identifier: a brand and a model number, a colourway, a year. Buyers find items by typing something specific. "Blue jumper" is not something anyone types.
- Is light for its value. See the postage section. Value density is the whole game.
- Has finite supply. Discontinued, vintage, or produced in limited quantity. Anything currently on a shelf at Target or Argos competes with a new one.
- Is defect-tolerant. A scuffed cast-iron pan is still a cast-iron pan. A scuffed evening dress is unsellable.
- Has buyers who are looking for it rather than browsing. Replacement parts, discontinued crockery patterns and camera accessories all have buyers with an unmet specific need, which converts far better than aspiration.
Categories that continue to satisfy those tests:
- Technical and outdoor apparel with model names. Specific jackets, specific fleeces, specific boots. The brand and model are printed inside, buyers search by them, and the garments are built to survive a second owner.
- Workwear and uniform. Sizes at the extremes, discontinued colourways, and safety-rated boots.
- Camera glass and accessories. Lenses hold value, are searchable by exact designation, weigh little relative to price, and are tolerant of cosmetic wear.
- Hard goods with a serial or model plate. Kitchen mixers, sewing machines, power tools, vacuum cleaner attachments, replacement carafes and lids.
- Spare parts and components. The single most under-rated category. Buyers who need one specific missing piece are price-insensitive and do not return things.
- Craft and sewing supplies. Discontinued fabric, patterns, yarn in dye lots, notions. Light, searchable, non-returnable in practice.
- Board game and hobby components. Complete out-of-print games, and also individual pieces from incomplete ones.
- Local-only heavy goods. Solid wood furniture, tools, exercise equipment, appliances. These flip on Facebook Marketplace with no fee and no postage, and nowhere else. The trade-off is that you must be present for collection.
Categories that have largely stopped working:
- Fast fashion. Supply is effectively unlimited, the brand carries no search demand, and the sell-through is close to zero.
- Mass-market DVDs, CDs and paperbacks. The retail price collapsed and the postage did not. On eBay US, ordinary books also carry the 15.3% rate, the highest of any common category.
- Generic glassware and crockery. Heavy, fragile, low value. The postage and the breakage rate together exceed the sale price.
- Untested electronics of any kind. See the legal section.
- Anything Amazon sells new for less than your postage. Check before you list, not after.
Two more warnings specific to sourcing at the bins:
- Do not buy designer handbags, watches or high-value branded goods at outlet prices expecting them to be genuine. They mostly are not. Platform brand-protection programmes will remove your listings and repeated removals put your account at risk. If you cannot authenticate a category yourself, leave it.
- Do not buy anything you cannot test in a category where non-function is invisible. Untested audio equipment is a coin flip you pay to lose.
Legal Exposure Most Guides Omit
Reselling used goods is regulated. The rules differ by country and this section is not legal advice; check your own jurisdiction.
United States: the CPSC rules
The Consumer Product Safety Commission publishes a Resellers Guide to Selling Safer Products aimed directly at thrift stores, consignment stores and individuals selling on auction websites. Its key points, quoted from that guide:
- "CPSC's laws and regulations apply to anyone who sells or distributes consumer products. This includes thrift stores, consignment stores, charities, and individuals holding yard sales and flea markets."
- "It is illegal to sell any recalled product" unless it has been repaired in accordance with the recall.
- You are not required to test used products for safety, but you "cannot knowingly sell products that do not meet the requirements of the law", and the guide states plainly that "ignorance of the law is not an excuse."
- Most cots and cribs manufactured before June 2011 may not be resold.
- Children's metal jewellery must comply with the federal lead limit of 100 parts per million.
- Also prohibited: toys and children's articles and furniture with surface coatings containing lead above the specified limit; products intended primarily for children aged 12 or younger with lead content over the limit; and durable infant and toddler products such as play yards, infant walkers, bath seats and bed rails that are missing parts, wobbly or unstable.
- The guide notes that CPSC recalls between 300 and 500 products annually, and directs resellers to check SaferProducts.gov before taking a product into inventory.
The practical rule that falls out of this: check the recall database before listing any children's product, nursery item or powered appliance. It takes a minute and it is the difference between a sale and a federal violation.
United Kingdom: fire safety, distance selling and trader status
Upholstered furniture. The Furniture and Furnishings (Fire) (Safety) Regulations 1988 apply to second-hand furniture. Regulation 14 covers furniture previously supplied to someone who acquired it other than for the purposes of a business of dealing in furniture (that is, ordinary household furniture) and requires it to meet the ignition requirements in regulations 5, 6 and 8. Regulation 4 excludes goods manufactured before 1 January 1950. In effect: a genuinely antique sofa is outside the rules; a 1990s sofa with no fire label is a problem, and Trading Standards treat it as one.
Distance selling and returns. GOV.UK's guidance for businesses is explicit. For online, mail and telephone sales, "You must offer a refund to customers if they've told you within 14 days of receiving their item that they want to cancel. They have another 14 days to return the item once they've told you." You must refund within 14 days of receiving the item back, you must also refund the cost of standard delivery, and "It's illegal to restrict or take away customers' rights or to mislead them about their rights, for example by displaying a sign that says you do not accept returns or offer refunds." The "no returns accepted" line that appears on thousands of second-hand listings is not enforceable against a UK trader.
The same guidance also requires repair or replacement where a customer returns a faulty item within six months unless you can prove it was not faulty when sold, and notes that customers have up to six years to make a claim (five in Scotland).
Trader status. Buying to resell makes you a trader for both consumer law and tax. That is not optional, and it is the reason the eBay UK business fee schedule rather than the free private-seller schedule applies to you.
Canada and Australia
Rules on product safety, recalls, consumer guarantees and tax registration differ materially in both countries and this audit did not research them. Canadian sellers should check Health Canada's consumer product safety rules and the CRA's guidance on business income; Australian sellers should check the ACCC's product safety requirements and the ATO's guidance on whether a hobby has become a business. Do not assume US or UK rules transfer.
Tax
United States
The IRS reporting threshold for Form 1099-K from payment apps and online marketplaces is payments totalling over $20,000 in more than 200 transactions. The IRS page carries an unambiguous rider: "Whether or not you receive a Form 1099-K, you must still report any income on your tax return. This includes payments for any goods you sell (including personal items such as clothing or furniture sold at a gain)."
The reporting threshold and the taxability threshold are different things. Not receiving a form does not make the income invisible. Some states set their own lower reporting thresholds. Check with your state revenue department rather than assuming the federal number applies.
Sales tax on your own sales is generally collected and remitted by the marketplace under marketplace facilitator rules, which is why eBay's fee page lists sales tax as part of the total amount of the sale on which it charges commission. The sales tax you paid when buying stock is part of your cost of goods.
United Kingdom
- The trading allowance is £1,000 of gross trading income per tax year. GOV.UK states that if annual gross trading income is £1,000 or less you may not have to tell HMRC, though there are circumstances requiring Self Assessment anyway, and you must keep records. Note that this is gross, not profit. £1,200 of sales with £900 of costs is over the threshold.
- Digital platforms report you to HMRC. Under rules in force since 1 January 2024, platforms collect your name, address, date of birth and National Insurance number and report your platform income annually, by 31 January following the calendar year. Your details are not reported if you make fewer than 30 sales of goods in a calendar year and receive less than €2,000 (about £1,700) for those sales. Above either, you are reported.
- HMRC is explicit that a report does not automatically mean tax is owed, and equally explicit that "If you buy or make goods to sell at a profit, you're likely to be trading and will have to pay tax on your profits."
Records worth keeping from day one
Whatever the jurisdiction, the records that make the difference in an enquiry are the ones you cannot reconstruct later:
- Date, source and cost of every item, ideally photographed with the receipt.
- Mileage or transport cost per sourcing trip, with dates and destinations.
- Every platform fee, label cost and packaging purchase.
- Sale date, gross, fees, net, and the platform's own payout statement.
A spreadsheet with one row per item is enough. What is not enough is a shoebox of unlabelled receipts and a memory of what things cost.
Storage: The Cost That Arrives Quietly
Inventory needs somewhere to live, and the volume tiers of sourcing generate it faster than the listing rate consumes it.
Published figures for US self-storage costs disagree substantially. SpareFoot reported the average monthly rental cost of a 10x10 unit at $74.98 as of February 2026, describing it as a five-year low, while a separate SpareFoot industry statistics page put the national 10x10 average at $119. RentCafe's self-storage report put national rates at $133 per month in May 2026. These are industry indices from storage marketing companies, not a statistical agency, and they measure slightly different things. Asking rates, move-in rates and in-place rates are not the same number. Treat the range of roughly $75 to $135 a month as indicative rather than precise, and check local quotes.
The point is not the exact figure. The point is what it does to the model. Return to the earlier arithmetic: 200 listings, 4% monthly sell-through, $12 average net, gives $96 a month. A storage unit at any figure in that range consumes the entire profit and then some. Storage is not a cost you add once you are successful; it is a cost that determines whether you can become successful.
Storing at home has a different cost that is real but not billed: the room, the smell of unwashed textiles, the relationship strain, and the risk that a household contents insurance policy excludes stock held for business purposes. This audit did not verify any specific insurer's exclusion: read your own policy wording, because a garage full of resale inventory destroyed in a flood is exactly the claim an insurer will examine closely.
Time: The Cost Nobody Prices
Every item passes through the same pipeline: source it, transport it, wash or clean or repair it, photograph it, measure it, research a price, write the listing, answer questions, pack it, take it to a drop-off, and sometimes process a return.
A realistic estimate is 15 to 30 minutes per item for a competent seller working in batches, and considerably more for the first hundred items. This is an estimate based on the number of discrete steps, not a sourced measurement, and it will vary enormously with category. A t-shirt is faster than a camera lens, and a camera lens is worth more.
Take the low end. Two hundred items at 15 minutes each is 50 hours of work before a single sale. Add a weekly sourcing trip of four hours including driving, and a monthly total of perhaps 30 to 40 hours is ordinary for a portfolio of that size.
Compare that against the wage floor. In the UK, the National Living Wage for workers aged 21 and over is £12.71 an hour from April 2026. Thirty-five hours at that rate is roughly £445. A portfolio producing under £200 a month is paying you well under half the legal minimum for employed work, with no holiday pay, no pension contribution and no sick pay.
That is not an argument against flipping. It is an argument for knowing which side of the line you are on, and for measuring hours from the first week rather than the first year.
A Worked Month
Every figure below is either sourced above or explicitly marked as an assumption. Nothing here is a claim about what anyone actually earned.
Assumptions (mine, not sourced): one sourcing trip a week to an outlet at $1.99 per pound; 30 lb bought per trip; average item weight 0.75 lb, so roughly 40 items per trip; 160 items sourced in the month; 100 items actually listed, because listing is the bottleneck; monthly sell-through of 6% against a growing portfolio averaging 250 active listings; average sale price of $28 on eBay US in ordinary categories.
Costs:
- Stock: 4 trips × 30 lb × $1.99 = $238.80.
- Driving: 4 trips × 30 miles round trip. At the reader's own fuel cost. Call it $40 to $60, unsourced.
- Listing time: 100 items × 20 minutes = 33 hours, unpaid.
- Packaging: poly mailers, tape, tissue. Roughly $0.40 per shipped item, unsourced estimate.
Revenue, at 6% of 250 listings = 15 sales:
- Gross item revenue: 15 × $28 = $420.
- Buyer-paid postage collected, say $6 average: $90. Total amount of sale: $510.
- eBay final value fee at 13.6% of $510: $69.36. Plus 15 per-order fees at $0.40: $6.00.
- Actual label cost at $6 average: $90.
- Packaging: 15 × $0.40 = $6.00.
- Insertion fees: none, assuming under 250 listings.
Net for the month: $510 received, minus $69.36 in commission, minus $6.00 in per-order fees, minus $90 in labels, minus $6 in packaging = $338.64. Subtract stock at $238.80 and fuel at $50, and the month clears roughly $50.
Against 33 hours of listing plus about 12 hours of sourcing and driving, that is about a dollar an hour.
Now change one variable. Hold everything else and raise the average sale price from $28 to $70 by sourcing fewer, better items. 15 sales at $70 gross plus $6 postage is $1,140 total sale amount, commission $155.04, per-order fees $6, labels $90, packaging $6, leaving $882.96, minus the same $288.80 of stock and fuel, for roughly $594. Same hours. Twelve times the profit.
This is the finding. The lever is average sale price, not listing count. Everything in the volume-oriented advice pushes you the wrong way.
Scams and Losses That Target Sellers Specifically
- The Google Voice verification code scam. The FTC's consumer alert describes it precisely: scammers target people posting things for sale on sites like Craigslist and Facebook Marketplace, express interest, then claim they want to verify you are a real person, send you a verification code by text and ask you to read it back. They use it to open a Google Voice number linked to your phone number, which they then use to defraud others, and sometimes to gather enough information to open accounts in your name. The FTC's rule is absolute: do not share a verification code with anyone who contacted you first.
- Item-not-as-described abuse. On eBay, the buyer opens an INAD case, the seller pays return shipping under the Money Back Guarantee, and a rising INAD rate can trigger the 5% or 6% fee surcharge described earlier. Some buyers know this and use it as a negotiating position. The defences are photographic: photograph every flaw, photograph the item packed, and keep the photos.
- The empty box and the swap. A returned parcel containing a different, broken, or absent item. Film yourself opening returns. It is not paranoia if the platform's dispute process asks for evidence.
- Chargebacks. eBay charges $20 per dispute in the US and £16.80 including VAT in the UK where you are found responsible, on top of losing the item and the money.
- Local-collection fraud. Counterfeit notes, "my courier will collect and pay you", payment screenshots that are images rather than transactions, and the classic overpayment-and-refund-the-difference. Cash in hand, counted, in a public place, or a bank transfer you have personally confirmed in your own banking app before the item leaves your hands.
- Off-platform solicitation. eBay's fee page states that if you offer or reference contact information in the context of buying or selling outside eBay, you will be charged a final value fee even if the item does not sell, calculated on the highest relevant price. The buyer suggesting you complete the sale by direct transfer is either a scammer or is costing you a fee.
Who should skip this
Explicitly, this is a bad fit if:
- You need predictable weekly income. Sell-through is lumpy. A month with two good sales and a month with none are both normal. Nothing about this model produces a wage.
- You do not have transport and free storage. Once you are paying for a unit, the numbers in the storage section apply, and they are brutal at small scale.
- You have back, joint, dust or mobility limitations. The cheap tiers of the sourcing hierarchy are physically demanding in dirty environments. The tiers that are not physically demanding are the expensive ones, where the margin is thin.
- You dislike administration. This is a business of records: cost basis, mileage, fees, disposals, tax returns and platform correspondence. The sourcing is the fun part and it is perhaps a fifth of the work.
- You are financing inventory. Buying pallets or auction lots on credit converts a low-return activity into a leveraged one. The failure mode is a house full of stock and a monthly payment.
- You want it to scale linearly. It does not. The bottleneck is your listing hours, and hiring someone to list requires a margin per item that outlet-sourced clothing does not produce.
- You are in the UK and intend to register as a private seller to avoid business fees. That misstates your status to the platform, deprives your buyers of their statutory rights, and does not change what HMRC thinks you are.
A Realistic First 90 Days
Days 1 to 14: measure before you buy. Pick two categories you already know something about. Use eBay's sold-listings filter and, if you have it, Terapeak, to look at thirty comparable items in each. Record sale prices, how long listings sat, and how many identical items are currently active. That last number is your supply check.
Days 15 to 30: sell what you own. List twenty items from your own house. This costs nothing, teaches you the listing flow, the photography, the postage weights and the packing, and produces your first feedback without risking capital. Record the time each item takes. That number is the input to everything else.
Days 31 to 60: source small and deliberately. One trip. A strict budget. Buy only items you have personally checked against sold comparables at the shelf. Impose a hard rule that everything bought gets listed within 72 hours, and if you cannot keep it, buy less next time.
Days 61 to 90: compute your own numbers. Active listings, sales, sell-through, average net per sale, hours worked. Multiply. Divide by hours. If the hourly rate is below your local minimum wage and the trend is flat, the correct decision is either to change the category towards higher average sale price, or to stop. Both are respectable. Continuing without measuring is not.
Regional Notes in Brief
- United States. eBay 13.6% plus per-order fee for most categories, Mercari 10%, CPSC recall rules bind individual sellers, 1099-K reporting at over $20,000 and more than 200 transactions with all income reportable regardless, state thresholds may be lower.
- United Kingdom. eBay private selling is free but does not apply to you if you buy to resell; business fees run around 9.9% to 12.9% by category plus a per-order fee and a 0.35% regulatory operating fee; £1,000 trading allowance on gross income; platform reporting above 30 sales or €2,000; statutory 14-day cancellation rights you cannot contract out of; fire safety regulations bind second-hand upholstered furniture made after 1950.
- Canada and Australia. Not researched here. Check Health Canada and the CRA, or the ACCC and the ATO, before you start. Assume nothing transfers.
The Summary Nobody Puts in the Headline
Thrift flipping is a real trade with a long history and no barrier to entry, which is precisely why the margins are where they are. The individual finds are genuine. The published fee schedules, the published postage rates and your own honestly measured sell-through will tell you whether the aggregate is worth your time.
Three things decide it, in order:
- Average net per sale. Driven by what you buy, not how much.
- Sell-through rate. Driven by supply scarcity in your category, not by effort.
- Hours per item. Driven by process, and the only one of the three you can improve immediately.
Listing count is a consequence of those three, not a cause of income. Any guide that tells you to hit a listing target without telling you your sell-through has skipped the arithmetic.
