The most common reason for a card being declined is that you have made an error with the number, expiration, or security code. For security reasons, we also require that orders paid by credit/debit card be shipped to the billing address of the card being used.
If you need your order shipped to an address other than the billing address (where you receive your statements), please select PayPal checkout which does not require a PayPal account and allows you to pay with credit/debit.
