TCGshopkeeper

Capture Cardmarket offers into buyout lists and calculate buyout prices (70-100%). Evidence codes, PSA 10 upside, contracts in PRO.

TCGshopkeeper (formerly Cardmarket Buyout Helper) — a buyout assistant for trading-card vendors who buy cards from customers on Cardmarket. FREE FEATURES • Captures an offer straight from the Cardmarket page you are viewing — card name, condition, price, and a link to the offer. • Calculates a buying price (70–100% of the offer price) and saves the card into a buyout list. • Keeps any number of buyout lists — copy and move cards between them. • Customer wishlists with price tracking. • Evidence codes for buyouts and cards, ready for inventory records. • JSON backups of everything, including an automatic weekly backup. TCGSHOPKEEPER PRO A paid subscription adds: • A printable purchase contract with your company details and named templates. The contract is a Czech-law document and prints in Czech. • Quick buyout: add a card with one click, based on the cheapest NM offer (respects the active page filter). • Filter presets — save the current Cardmarket filter and re-apply it later. • The PSA 10 upside on the Cardmarket page — an estimate of the profit if the card grades as PSA 10. • The PSA 10 view in the panel — a whole buyout ranked by grading upside, with your grading cost applied. • Blank cards — add a card by hand, for anything not on Cardmarket. • Buyout download — export a buyout to XLSX or JSON. ACCOUNT An account is optional and exists only to pay for PRO — sign in with Google or with a six-digit e-mail code. The account carries only who you are and what you have paid for. Subscriptions are processed by Stripe. PRIVACY Buyout lists, wishlists, and contracts stay in your browser (chrome.storage.local) and are never sent anywhere. The extension contains no analytics and no ads. If the extension itself fails, it sends a technical error report so we can find and fix the fault — it carries no buyout data and no identity.
