When buying in Portugal the User can choose to pay by Multibanco, Paypal, Credit Card (trough Paypal). Users from outside Portugal can only pay by Paypal / Credit Card.
For automatic processed orders that were made using payment by Multibanco, Paypal or Credit Card, the User will be immediately informed by email how to proceed with payment. For orders made using payment by Multibanco, the payment references will also be shown immediately after the order registry.
Paypal is the system used by Susanagateira® to receive payment made either through Paypal accounts and Credit Cards (VISA, MasterCard and American Express).
To proceed with your payment using a Credit Card (process made through Paypal) the User does not need to have a Paypal account and the Paypal system will work only as an interface to assure the payment, achieving one of the highest security levels in online payment.
