About Cardheist

What we do

Cardheist tracks prices on Pokémon, Magic, Yu-Gi-Oh!, One Piece and Lorcana sealed products across multiple retailers. We started with Pokémon TCG — the other games are routed but coming online as we onboard scrapers and retailers. Single cards are out of scope: we focus on Booster Boxes, ETBs, Bundles, Tins and other sealed product, where price differences between retailers actually matter.

How it works

• Daily scrape. Every retailer in our index is scraped at least once a day. Most prices on Cardheist are less than 24 hours old.
• Price history. We store every change to a deduplication-aware history table — so the highest price we've seen becomes the implicit RRP, and you see the real low.
• Best-price ranking. Open a product and we sort retailers by total price, so the cheapest in-stock option is always at the top.
• No fakery. "Was/Now" badges use the real historical max, not invented reference prices.

How we make money

Some retailers pay us a small commission when you click through and buy. It never affects ranking or which products we feature, and you pay the same price either way. If a retailer doesn't have an affiliate program, we still list them — the comparison is for you, not for them.
