Why

Buying in is the same job every time. You just do it by hand.

Find the price, type it into a spreadsheet, convert the euros, work out the percentage. Fifty times in an afternoon. Here it is all in one place.

No retyping

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.

No second-guessing the rate

Done locks the rate and the prices. A closed buyout list stays as it was.

Excel for your books and your shopPRO

XLSX export for your accountant, your stock or an import into your web shop. You pick the columns.

Fewer mistakes

Nothing is retyped by hand, so the price, rate and total stay right. The more cards you buy, the more it shows.

Questions

Before you install

What is TCGshopkeeper?

TCGshopkeeper is a Chrome and Brave extension for card shops and event traders 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. Install the extension from the Chrome Web Store, then start PRO inside it: sign in with Google or an emailed code, and the first 14 days are free. Payment runs through Stripe and you cancel in the extension. The free plan needs no account.

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.

How does it read a card's condition?

It does not read the card. It copies the condition the seller has already set on the Cardmarket offer row — MT, NM, EX, GD, LP, PL or PO — onto your buyout list, with the price and the quantity. Grading a card you are holding is a separate job, and our Cardmarket condition guide sets out what each of the seven grades means.

Where are my buyout lists kept?

In the browser, in the extension's own storage. Your buyout lists are never uploaded. The free plan needs no account; PRO needs one. 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. It follows Czech buyout practice, so outside Czechia have it checked before you use it.

Can Cardmarket sanction my account for using this?

The extension only reads the page you have open, and it never buys, sells or messages on your behalf. Your use of Cardmarket is still governed by Cardmarket's own terms, and we are not party to that relationship — read § 07 of our terms before you install.

What happens when Cardmarket changes its site?

Capture can break, because the extension reads Cardmarket's pages. We fix it as fast as we can, but we cannot promise when, and a change on Cardmarket's side is not a defect of the service. Your buyout lists are unaffected — they are on your machine.

What if you stop building it?

We give 60 days' notice, refund the unused part of any PRO period pro rata, and the free version keeps working in your browser. TCGshopkeeper is not affiliated with Cardmarket, PSA or Google.

Less maths. More time for the business.

Installing takes a minute. The free plan needs no account and your lists stay with you.
