Disclaimer

Last updated 8 September 2026. The plain-language version, and part of the terms of use. It is short because the point is simple.

Every number here is an estimate

SleeperLot shows predicted closing prices, reference prices drawn from active listings, and the gap between them. These are statistical estimates computed from public listing data. They are not appraisals, not offers, and not a guarantee of what any item is worth or what it will sell for. When we show a range with an n next to it, the range is the claim and the n is how much evidence sits behind it. A range built on three comparables is a weaker claim than one built on forty, and we say so rather than hide it.

We are wrong some of the time, on purpose

An 80% interval is expected to miss about one close in five. On the current window it is not hitting that: predicted ranges contained the real close — of the time across — scored closes, against a 80% target — so the ranges are narrower than the evidence supports, and we are publishing that rather than widening the claim. Our track record publishes every call against the real outcome so you can see how often that happens, and in which direction. If the published miss rate is not one you are comfortable with, do not act on the estimates.

Bidding is your decision

SleeperLot never places, schedules, or recommends a specific bid. It does not auto-bid, snipe, or interact with any marketplace account on your behalf. A human reads the page and a human decides. Anything you bid, win, pay for, or fail to resell is your own responsibility, including shipping, fees, condition surprises, and the item simply not being what its title said.

We do not know the item

We match listings to an item class from titles, structured specifics, and category. We never inspect the item. A listing can be misdescribed, counterfeit, damaged, or missing parts, and our estimate will not know. Read the listing. Look at the photos. Check the seller.

Independent of every marketplace

SleeperLot is independent. eBay, ShopGoodwill and every other auction platform neither endorse nor sponsor it, we are not their agent, and we have no access to your account. Listing data is used under those platforms’ published terms and only for as long as it is publicly available.

Nobody pays us when you buy. No link on this site is an affiliate link, and we have never been paid for a click. We intend to join the eBay Partner Network; if we do, this paragraph is replaced by one saying so, and the commitment below holds either way.

Either way, being paid never changes what we show you or the order we show it in. Nothing in the code that decides which lots appear, or how they rank, is allowed to read anything to do with a commission — not the campaign, not eBay’s per-category rates, nothing. That is enforced by a test that fails the build, not by a promise. We also never take a cut of what you sell, and we are paid nothing by any seller.

Not financial advice

Nothing on this site is investment, financial, tax, or legal advice. Resale margins shown are arithmetic on estimates, before your own costs, and they carry the same uncertainty as everything else here.
