VISA and rarely Mastercard are the only credit cards accepted to process pharmaceutical orders. Viagra without prescription cannot be offered for sale using Paypal to pay for the purchase. There can, however, be an agreement made between a buyer and seller for this transaction. The buyer may send a required amount to the Paypal account of a seller and a seller will then ship the order to the customer after the payment is made into his Paypal account. Not all countries allow the use of Paypal for this, or any transaction.
