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.
