You may pay with either credit or debit cards, PayPal or Multibanco (if you have a Portuguese bank account). PayPal and Stripe manages all the banking transactions. We do not store any credit card numbers.
If you can’t pay with your credit or debit card it could be because the card was issued in a different country. Our PayPal payment system automatically blocks this kind of transaction for safety reasons, in order to minimize online fraud. If you can’t use your card, we recommend you to choose a different payment method.
