Insufficient Funds
Please check the account associated with your card to ensure there are funds available for your purchase. If you find that there are sufficient funds, your card may have been declined for one of the reasons listed below.
Some banks use "Insufficient Funds" as a generic error message to merchants for cardholder protection. If you do have sufficient funds on your card, you may also want to check with your bank to make sure there are no holds on your card.
Address Verification System (AVS)
When entering your payment information, make sure to enter your billing address exactly as it appears on your account statements. Everything - including hyphenation and spacing - must exactly match the information that the issuing bank has on record in order to pass the AVS check.
Note: If your transaction fails to pass this check, your credit card issuer may place a temporary hold on the funds for the attempted purchase (this hold may last several days, depending upon their policies).
