We accept Visa, MasterCard, Maestro, Discover, PayPal, and Apple Pay.
All the payments go through an automatic verification process. When a payment fails the authorization process, you might see the messages 'Do not Honor' or 'Processor declined'. These are fairly generic responses from the bank declining a transaction, for a range of reasons which only the bank knows. This could be because our company is based in Barcelona, Spain; they might reject international transactions automatically. Please ask them whether that's the case.
Alternatively, you could use another credit card or PayPal account.
