Our payment system should accept a debit, gift or prepaid card if it supports online transactions and international transactions (we're based in Europe - WalMart and Vanilla Visa gift cards, for instance, don't support transactions outside the US and Canada, according to user reports).

As a workaround, if the card doesn't support international transactions, you could try sending funds to a PayPal account beforehand and then use that account to make a purchase on our site. Of course, the choice is yours :)
