Click an offer and the card is on your buyout list with its price, condition and quantity.

No calculator

The percentage of market price, the euro rate and the total in € and Kč work themselves out.

Questions

Before you install

What is TCGshopkeeper?

TCGshopkeeper is a Chrome and Brave extension for card shops and fair vendors that buy in on Cardmarket. Click an offer and the card is on your buyout list, with the percentage of market price, the euro rate and a running total in € and Kč. The free plan is the buyout itself. PRO adds saved filters, PSA 10 upside, a Czech purchase contract and Excel export.

How much does TCGshopkeeper cost?

The buyout plan is free, with no cap on lists or cards. PRO is 500 Kč a month at the early-bird price (was 990 Kč), about €20. You can try PRO free for 14 days. You install both from the Chrome Web Store. No account for the free plan.

How do card shops run a Cardmarket buyout with it?

Start a buyout list and set your percentage of market price. Click offers on Cardmarket and the cards land on the list. The running total in € and Kč stays at the top. Hit Done and the rate locks. PRO shops can then print a Czech purchase contract and export the list to Excel.

Where are my buyout lists kept?

In the browser, in the extension's own storage. Nothing is sent anywhere and you do not need an account. Export a backup to a file whenever you like and restore it on another machine.

Does it work in Brave?

Yes. The extension runs in Chrome, in Brave and in other Chromium-based browsers.

Do I have to be signed in to Cardmarket?

Ordinary browsing is enough to capture offers. The extension reads what you can see on the page — it buys and sells nothing on your behalf.

Is the free version capped in any way?

No. The number of buyout lists and cards is not limited. The plans differ in features, not in limits.

Is the purchase contract legally usable?

It is a draft to print and sign, based on ordinary buyout practice — it carries the subject, the amount in figures and in words, an annex with the breakdown, and accounting codes. You and your accountant are answerable for the final wording.

Less maths. More time for the business.

Installing takes a minute. You do not need an account and your data stays with you.
