I have had the same problem as everyone above. Tries sevarla valid cards. America Express reports "pending" charges show up on my account and AE is prepared to authroize the payment. However the postal service system is unable to complte the transaction for reasons unknown. I even set up a new usps.com account but it too failed.
I see click and ship labeles at the psot office so the system seems to work for a few people.
