What you pay at checkout, paying with your balance, and currency.
Cardmine keeps checkout transparent: you always see the full total before you pay, with no surprise charges afterwards.
Your checkout total is made up of:
Payment processing is included in that total — there is never a separate charge later.
The service fee funds Buyer Protection and keeps the marketplace running. It is charged per seller order, not per card, so combining several cards from one seller into one order keeps smaller purchases affordable. The exact fee is always shown before you confirm.
If you have a Cardmine balance — for example from a refund, or from selling cards yourself — you can put it toward an order at checkout. Your balance lives in the Wallet tab of your profile. If your balance covers the whole order, there is nothing left to pay.
Prices and totals follow the currency for your region, which you can change in the site header. For a full breakdown of who pays what, see the Fees page.
