Pricing and accuracy

How pricing works: real recent sales

Where your price estimate comes from: real sold prices from marketplaces and category specialists, not an AI guess.

Watch: How to Price Items to Sell on eBay (Read Sold Comps, Not Asking Prices)

Your estimate is built from real sold prices (resellers call them sold comps), meaning what buyers actually paid, not what sellers are asking.

Where the numbers come from

Every scan runs a live search across the sources that know your item best:

  • eBay sold listings first, for everyday resale.
  • Poshmark and Mercari sold listings where they fit.
  • Grailed for vintage clothing and AbeBooks for books.
  • A barcode in the photo (ISBN, or a CD or record's barcode) pins the exact edition through Google Books or Discogs.
  • Our own archive of over a million recorded sales.

The exact edition gets priced as itself instead of being lumped into one generic search. Because it is not one fragile source, pricing keeps working when any single site goes dark.

What you get back

  1. A price range with low, suggested, and high points.
  2. Recent sales: actual sale prices and clickable links.
  3. Listings for sale now: current asking prices.
  4. Competition and how fast it sells: how many are for sale against how many sell.
  5. You keep (after fees): your take-home after the marketplace's selling fee.
  6. A plain note next to the price when the category or the matching sales run wide.

Why this beats checking sold listings by hand

Manual research usually takes 5 to 10 minutes per item and covers one platform. A scan searches sold data across several platforms at once, factors in the condition and specifics visible in your photo, returns results in seconds, and writes a title, description, and suggested price at the same time.

How accurate is it

Accuracy depends on image quality and how common the item is. Clear photos and multiple angles in one scan improve it noticeably. For high value or rare pieces, open the comparable sales we list and check them yourself before you buy or list.

Seeing the recent sales

Every scan shows the recent sales behind the price, with links, and that includes your free first scan. After the free scan, plans start at $5 a month and credit packs at $3 for 5 scans. Works on web or mobile.
