How Pokemon Deal Finder Works
Last updated 2 September 2026
The site runs the same steps around the clock: find new eBay listings, work out which exact card each one is, compare the price against real sold-market data, filter out the bad and wrong ones, run an extra image check on the riskier ones, and drop anything that has gone stale. Here is that journey in order.
1. Listings are discovered
New listings are pulled continuously from the eBay Browse API, in the Pokemon single-cards category, across six marketplaces — the United States, United Kingdom, Australia, Canada, Germany and Italy. Listings already on the site are re-checked on a rolling schedule to confirm they are still active and still a deal. The card catalogue and sealed products are re-synced daily.
2. Each listing is matched to the exact card
eBay search returns loosely related results, so every listing is matched to one exact catalogue printing before it is trusted. The name and set have to be present, and identity conflicts — a different collector number, a different card form such as Mega versus non-Mega, an ex / EX / GX distinction, or a different language — cause the listing to be dropped rather than forced onto the closest card. English and Japanese printings are always kept separate.
3. The price is compared against real data
The total a buyer actually pays — item price plus shipping — is compared against a recent-sold market reference for that card in its condition, from PokemonPriceTracker. Raw cards are priced against the condition the seller describes; graded cards are priced only against sold comps for that exact grading company and grade. A market reference is an estimate of recent sold value, not a guaranteed price, and it moves.
4. Bad and wrong listings are filtered out
A listing only makes the site if it is meaningfully below its market reference and the seller passes trust checks. Listings that look like the wrong card or wrong printing, priced far below market, damaged, in an unverifiable condition, or not actually a single card at all — empty wrappers, sealed product, merchandise, proxies — are excluded rather than shown.
5. Higher-risk listings get an extra image check
Selected higher-risk listings receive an additional automated check that compares the listing photo with the card's expected official printing. It can catch a photo that shows an obvious physical counterfeit, and a photo that shows a genuine card of a different printing than the listing claims; both are hidden. The site's most prominent recommendations require a high-value, deeply discounted non-graded listing to have passed this check first. This is automated screening, not card authentication or grading.
6. Stale and ended listings are removed from promotion
Auctions known to have ended are removed automatically. A listing that goes too long without being re-seen in a scan stops being shown as a live deal, sooner for higher-value cards, and a separate bounded process re-checks individual eBay items and retires ones that have ended or sold. Every figure on the site is accurate only as of the last time the listing was seen.
7. You click through to the exact eBay listing
Each deal links straight to the one eBay listing it was priced from — not a search or an eBay catalogue page. Purchases, payment, shipping, returns and support are handled entirely by eBay and the seller. Always check the listing's own photos and description before buying.
