Mispriced listings are not random. They come from sellers who do not know what they have, and that ignorance leaves consistent, recognisable traces in the listing itself.
Vague titles are the strongest single tell. Someone who writes "black jacket size M" is not searching for the model name because they do not know it, which means the listing will not appear for the searches that would price it correctly. The item is cheap because it is invisible, not because it is worthless.
Supporting signals: photos taken on a bed or floor rather than hung, no mention of condition, a round-number price like €15 or €20 that was clearly chosen rather than researched, and a profile with few listings and a clearing-out-the-wardrobe description.
The same signals appear on listings that are cheap for good reason. A vague title on a genuinely damaged item is still a damaged item. Before committing, get eyes on the specifics: ask for photos of the label, the inside seams, the soles or cuffs, and any area the existing photos conveniently do not show.
A seller who cannot or will not photograph the label is a seller you should walk away from, whether the reason is a fake, damage, or simple disinterest. The cost of asking is one message; the cost of not asking is the whole buy price plus the return dispute.
Genuinely underpriced listings do not last. If your check takes ten minutes because you are hand-searching sold prices in three markets, the good ones will be gone before you finish, and you will only ever get the ones nobody else wanted — which is a selection effect that quietly destroys the returns of this whole channel.
This is the argument for knowing your numbers in advance rather than looking them up in the moment. The resellers who win at arbitrage are not the ones checking hardest; they are the ones who already know what the model is worth and only have to verify the item.
On already-underpriced stock, usually not — the delay is a bigger risk than the few euros. Negotiate on items that have been sitting for weeks, where the seller has already learned the price is wrong and nobody else is competing for it.
Treat an unexplained deep discount on a commonly-faked brand as the primary hypothesis, not a lucky break. Ask for label, stitching and hardware photos, compare against genuine examples, and skip anything where the seller gets evasive. Chapter 8 goes into this properly.
