Credit card checkout is available for digital, and some merch purchases, made in British pounds, US, Canadian, and Australian dollars, Japanese yen, and euros. Depending on your credit card provider, you may not be able to complete your purchase in all of these currencies. Cards accepted are Visa, Mastercard, American Express, and Discover.
If credit card checkout isn’t available for a specific purchase (either because of currency restrictions or because you are buying certain physical goods), you may still be able to pay with a card via PayPal, even if you don’t have a PayPal account.
