My credit card has been declined, I keep getting this "Duplicate" error. What's up with that?

Our website has a built in fraud protection measure that prevents multiple cards from being used on the same order during the same session. In many cases, your first attempt may have been declined due to an incorrect postal code, phone number, or security code. If your transaction is declined, you can simply close your browser, re-open it, and begin your purchase again. Please pay close attention to the "billing address" information when you process the transaction a second time. If you continue to have problems, please contact us as your order will likely have been stored in our system and we can process the charge manually for you.
