On Quadriarteitaliana.com you can purchase and pay safely through Paypal, the most widely used payment processor in the world.
You can use your Paypal account (if you have one) or a credit/prepaid card, always through Paypal.
Alternatively you can pay by making a bank transfer to the following coordinates:
Maria Rosaria Paradisi Miconi
BNL BANCA NAZIONALE DEL LAVORO
Via dei Gracchi, 122 - 00192 Roma
In this case, processing the order will be a little slower and you will need to wait for the email to confirm the receipt of payment. To facilitate order fulfillment operations, we ask the courtesy to send the accounting copy of the bank transfer, with the ID number.
