You can choose from 3 different payment methods:
Whether or not a payment in USD is authorized can depend on the bank issuing the credit card used for payment. It can happen that banks prohibit their clients from paying in USD on foreign websites. It is your responsibility as the card holder to investigate with your bank on why your payment failed. If you face this situation, we recommend payment by Paypal on our site www.mariobertulli.com
If you are experiencing payment problems with your card, we suggest you to choose Paypal or to call us to try to pass your card on our internal payment terminal.
