Secondhand has no recommended retail price, so every figure is a reference point rather than a calculation. A thrift store prices by policy, an online seller prices against what a similar piece sold for, and both are anchored to a retail number the garment never sold at. Work out which of the three is doing the work and you can tell whether the tag is firm.
Three reference points, and only one is evidence
Cost is the weakest of the three. A seller who paid $8 at a flea market and wants a margin asks $20. The same shirt, priced from a donation bag by somebody who never thought about margin, is $6. What the seller paid tells you about their weekend, not about the garment.
Comparables are the only reference point worth using yourself. Sold listings from the last ninety days are evidence; asking prices are not, and a listing that has sat at an optimistic figure for a year proves only that nobody agreed. If four similar blazers sold at $45 to $60, then $50 is defensible and $120 is a hope.
The third is the anchor: the retail price of something adjacent. A coat with its tag cut out becomes worth $400 new once a seller finds a comparable style at that figure, which is how $180 starts to look like a favor. An anchor is a story about a garment nobody in the transaction has ever owned.
The platform cut decides what you pay
A seller who wants $50 in hand has to ask a different number on every platform, because the take rate differs. Work it backwards and the price gap between sites stops looking like snobbery and starts looking like arithmetic.
What a seller must ask to take home the same amount
| Platform | What the seller pays | List price to net the same (relative) | What the buyer pays |
|---|---|---|---|
| Vinted | Little or nothing; the buyer pays a protection fee | Lowest | List price plus a buyer protection fee |
| Depop | Check the current fee page | Varies | The list price plus shipping and any fees |
| Mercari | Check the current fee page | Varies | The list price plus any buyer fee |
| eBay | A percentage final value fee | Higher | The list price plus shipping |
| Poshmark | A commission on each sale | Higher | The list price plus a prepaid label |
| ThredUp | Consignment: a share of the sale | Not set by the seller | The listed price |
Two conclusions follow. A blazer listed higher on a commission-heavy platform and lower on a buyer-fee platform can be the same garment at the same seller margin, so the platform says something about fees rather than quality. And the rates move often, so check each platform's fee page before you compare (as of Oct 2026).
Why the same shirt is $4 here and $40 there
Most thrift stores run two pricing systems under one roof. The main rack is banded by garment type, so a shirt is a shirt and the price barely moves between a supermarket label and a good one. The cabinet marked vintage is priced by a person with a list of brands, which is how the same jacket costs ten times another on the same afternoon.
The logic is not greed. Supply is donated and quality is not, so a 1970s Levi's jacket and a 2010s mall-brand jacket arrive in the same black bag. Pricing both at $8 leaves most of the value on the rack, and pricing both at $75 leaves the second one unsold for a month. A Levi's piece carries real history, too: the company traces the blue jean to an 1873 rivet patent and has sewn on the Red Tab since 1936.
How to price something before you commit
Two minutes on a phone settles most decisions. Search the maker, filter to sold, and read the dates on the results rather than the figures, because one good sale two years ago says less than three average ones last month. Then subtract the work: a $120 coat needing $60 of tailoring costs $180, and a $90 coat that fits is the cheaper garment.
Six searches worth running before you pay

Heavy wool that survives decades, and a label size bearing no relation to a modern one. Compare the flat chest against a shirt you own.

Polo Country tweed blazer
A discontinued sub-label with a settled resale range, which makes it a good benchmark: ask four times the sold median and it stays unsold.
Check on MercariWhat a fair price is not
A fair secondhand price has nothing to do with what the garment cost new, and nothing to do with how much you want it while standing in the shop. It sits where recent sales for the same thing, in comparable condition, have completed, adjusted for anything that needs fixing. Decide your number before you read the tag, and notice how quickly your own figure moves once you like the garment.
