Buy from one seller. Save on shipping.
CardMatcher saves the offers you find across Cardmarket's product pages and finds the single seller who can supply everything on your list — cheapest total first, real shipping cost included.
Add to ChromeAlso works on Edge, Brave, Opera, Vivaldi and any other Chromium-based browser.
Everything you need to consolidate an order
Cross-card seller matching
Save offers from as many card pages as you like. CardMatcher finds every seller who can supply all of them in the quantities you need, ranked cheapest first.
Live shipping rates
Once a seller's country is known, CardMatcher calls Cardmarket's own official shipping calculator — the same amount they'd actually charge you, not a flat guess.
Automatic country detection
Each seller's location is read straight off the listing page. Got detected wrong, or missing? Correct it by hand in one click.
Card thumbnails on seller pages
See the actual card art directly in a seller's full stock table, instead of hovering the small camera icon over and over.
5 languages, 2 themes
English, French, Spanish, Italian and German, with a light or dark theme that can follow your system setting automatically.
Local by default
Your saved cards and settings never leave your browser. The only outbound request is the shipping calculator, and it only ever sends a country pair.
From four card pages to one order
Open a card's page
Go to the Cardmarket seller list for one card you want.
Save this card
A small panel appears — check the quantity, click Save.
Repeat for the rest
Do the same on every other card's page on your list.
Calculate
Open the extension — see every common seller, cheapest first.
A panel that follows your shopping, not a separate tab
The floating panel reads the offers already on the page you're viewing and remembers the quantity you need — no copy-pasting prices, no separate spreadsheet.
Card art right in a seller's stock table
Turn on thumbnails and every row in a seller's full stock list shows the actual card, so you can scan for what you need at a glance.
Good to know
Is this an official Cardmarket extension?✛
No. CardMatcher is an independent, unofficial project with no affiliation to, endorsement from, or sponsorship by Cardmarket or Sammelkartenmarkt GmbH & Co. KG. It only reads what's already shown on the pages you visit while browsing.
Does it need my Cardmarket password or account access?✛
No. There's no login, no account connection, and no automated buying. CardMatcher just reads the seller list on the page you're already looking at.
Where is my data stored?✛
Locally, in your own browser (chrome.storage.local). There's no account and no server of ours. The one exception is the live shipping-rate lookup, which sends only a country pair (never card data) to Cardmarket's own public shipping calculator.
How accurate is the shipping estimate?✛
When a seller's country is known, the shipping cost comes straight from Cardmarket's own official calculator — packaging fee and mandatory tracking over €25 included. If the country isn't detected or the route isn't covered, a simple adjustable per-zone estimate is used instead.
Why is a seller's country sometimes wrong or missing?✛
Detection reads the location icon Cardmarket shows next to each seller, which isn't always present. You can always correct it by hand in the results table.
Does it cost anything?✛
CardMatcher is free. If it saved you a few euros on shipping, there's an optional way to say thanks below.
Which languages are supported?✛
English, French, Spanish, Italian and German, switchable from the extension's own menu.
Does it work outside of Chrome?✛
Yes. Install it from the Chrome Web Store — it works the same way on Edge, Brave, Opera, Vivaldi and other Chromium-based browsers, not just Chrome itself.
