A listing
A page with a price, some numbers about the seller, and a description written to be persuasive. Most of the numbers are weaker evidence than they look, and one of them is worth more than the rest put together.
- What it is
- An item page with a price and a set of seller figures
- Where you meet it
- Inside the market, after login
- What it settles
- What is being offered and on what terms
- Cannot tell you
- Whether this particular order will go well

A listing header with the three useful fields marked in lime. Age, dispute rate and the delivery window tell you something. The completed count and the rating mostly tell you that the account has been busy, which is not the same claim.
What each number is actually made of
| Field | What it is derived from | Worth |
|---|---|---|
| Vendor since | When the account was created | Real. Accounts are cheap but time is not |
| Orders completed | Orders that reached a closed state | Weak. Volume, not quality |
| Rating | Ratings left by buyers, most of whom leave a good one | Weak. It compresses near the top and stops separating anyone |
| Dispute rate | Disputes opened against the account | The most useful single number here |
| Delivery window | Set by the vendor | Important, and not for the reason people think |
The delivery window is a deadline for you
It is not only an estimate of when a thing arrives. It is the date after which a dispute becomes appropriate, which makes it the single most important field on the page for reasons that have nothing to do with delivery. Write it down when you order. Its own page explains why filing before it closes costs more than most people expect.
What history predicts and what it does not
A long record with a low dispute rate predicts ordinary behaviour, and it keeps predicting it right up until somebody decides the future will be different. That decision is invisible from outside and the incentive runs the wrong way, because the more trust an account has built the larger the payoff from spending all of it at once.
This is not an argument against preferring established sellers. It is the argument for sizing an order so that being wrong about any single one is survivable.
What a description is written to do
Sell. That is not a criticism, it is the job of the text, and it means the description is the one part of the page carrying no evidence at all. Read it for what is being offered and for the terms, then stop. The fields above it were generated by the system from things that happened, which is a different category, and the useful reading of a listing is almost entirely in those.
Terms that belong on the page and not in a message
- The delivery window, because it is your deadline as much as theirs.
- What happens if it does not arrive, stated on the listing rather than promised in a conversation.
- Whether early release is expected. If it is, it should be written down where you can read it before ordering.
- Anything about paying differently. If that only appears once you are talking, it is not a term, it is a request.
