Payments can fail typically due to incorrect card information (expiration date, address information, or CVC), card restrictions set by the issuer, account balance, or if the transaction is different from the cardholder's spending habits.  Our payment provider blocks any transaction which is deemed high-risk, to prevent fraud, as required under the Red Flags Rule by the Federal Trade Commission.

But, we understand how frustrating it is not to be able to make your favorite purchase! So if your card is blocked after the transaction, please let us know so that we can look into it.
