Worst case, get Jenifer (jhandley) your blinded CC number (12*1234) and she can credit your account for the failed purchases. The problem is, our CC processor (CyberCash) is sending us an undocumented AVS (address verification service) code of "D". Currently we are failing those transactions until we get a response from them as to what that code means. You might verify you are entering the billing address for your credit card correctly.
