CardMatcher for Cardmarket

Save offers from several Cardmarket cards, then find the single cheapest common seller to buy them all in one order.

CardMatcher helps you buy several different Cardmarket cards from a single seller, so you only pay shipping once instead of once per card. HOW IT WORKS 1. Open the Cardmarket page for a card you want (the seller list for that one card). 2. A small panel appears in the corner — check the quantity you need and click "Save this card". 3. Repeat for every other card on your list. 4. Open the extension and click Calculate: CardMatcher cross-references every seller who can supply ALL of your saved cards in the quantities you need, and ranks them from cheapest to most expensive — shipping included. LIVE SHIPPING RATES Each seller's country is detected automatically from the listing. When it's known, CardMatcher calls Cardmarket's own public shipping-cost calculator to get the real shipping price for that seller → your country pair (packaging fee and mandatory tracked shipping over €25 included) — not a guess. If a seller's country can't be detected, or the route isn't covered by Cardmarket's calculator, a simple estimate by zone (same country / Europe / rest of world, adjustable) is used instead. You can always correct a seller's country by hand. CARD THUMBNAILS ON SELLER PAGES Optional setting: shows the card artwork directly in a seller's stock table, instead of the small camera icon you'd otherwise have to hover. OTHER FEATURES • Manual add/edit — fix a wrong price, quantity, or seller by hand, or paste offers in as text. • Light and dark theme, follows your system setting or your own choice. • 5 languages: English, French, Spanish, Italian, German. • Works entirely in your browser: your saved cards, offers, and settings stay in local storage — no account, no server of ours, nothing sent anywhere except the one shipping-rate lookup described above (and that only ever sends a country pair, never your cards or personal data). Not an official Cardmarket product — independent tool, no affiliation with Cardmarket / Sammelkartenmarkt GmbH & Co. KG. It only reads what's already shown on the pages you visit while you browse; it doesn't republish or redistribute any pricing data elsewhere.
