What happens on an eBay listing
- 1
Open any eBay card listing
Any of the ten eBay sites the extension supports. It reads the title, photo and item specifics and matches the listing to one printing in CardTrack's Pokémon catalogue — English or Japanese, raw or slabbed.
- 2
The value panel appears on the page
Raw and graded market values from completed sales, with the last few solds for that card underneath. Nothing to click and no credits used.
- 3
Read the verdict
The asking price, converted from £, € or AU$ where needed, is compared with the market value: below market, fair, or above market. Auctions show the verdict against the current bid.
- 4
Check the photo, not the title
If the photo shows a different card than the title claims — Base Set 2 sold as Base Set, the wrong card number — the panel flags it before you pay.
- 5
Grade it if you're serious
One click estimates a PSA-style grade from the listing photo with centering, corners, edges and surface sub-grades. Add the back photo for a two-sided estimate.
- 6
Watch it or walk away
Add the card to your CardTrack watchlist from the panel and get an alert when it lists below market again.
Deal, fair, or above market — answered on the listing
The verdict compares the asking price with what the card actually sells for, not with other asking prices.
eBay questions
Which eBay sites does it work on?
eBay.com, eBay.co.uk, eBay.de, eBay.ca, eBay.com.au, eBay.fr, eBay.it, eBay.es, eBay.nl and eBay.ie, plus eBay Live streams. Asking prices in other currencies are converted to US dollars for the comparison; the sold prices shown are the completed sales CardTrack tracks for that card.
Does it work on auctions as well as Buy It Now?
Yes. For auctions the verdict is against the current bid, so a card that reads as a deal now may not be one at the close — the market value stays on screen so you can set your own ceiling.
Where does the market value come from?
Completed sales first — eBay solds and Fanatics Collect hammer prices — cross-checked against live TCGplayer, Cardmarket and PriceCharting prices, updated daily. The same number the card's page on CardTrack shows.
Does eBay know I'm using it?
No. The extension reads the listing page in your browser and talks only to CardTrack. It does not bid, message sellers or change anything on eBay.
Is it free?
The price check, sold prices, mislabel warnings and deal verdicts are free and unlimited. AI photo grading uses your CardTrack account's monthly credit allowance.
Everything the extension does: the CardTrack Chrome extension. On TCGplayer, Cardmarket and the others: the marketplace panel. Card values without the extension: the card value checker.
