Free redemption codes for PayPal are codes of letters and numbers that uniquely identify a Merchant Gift Certificate. PayPal users can apply an available redemption code towards a purchase for the full amount of the gift certificate associated with the code.
PayPal users can use Merchant Gift Certificates that they receive to pay for purchases at the stores of the designated merchants by entering the unique redemption codes on the Payment Confirm page. If the total amount of a purchase is less than the value of a gift certificate, the customer can use the remaining balance later. If the total amount is more than the value of a certificate, the customer can pay the balance with another certificate, his PayPal account balance, a credit card or a bank account. It is only possible to use two or more certificates together if they are in the same currency.
When using redemption codes to pay for purchases, users may be required to provide a valid credit card or bank account for identification verification purposes although there is no extra fee applied on that secondary funding source.
It is the best practice to use the email address associated with or added to an existing PayPal account to receive a gift certificate confirmation.
