I pay online BC it is so much easier the stuff with the PO will happen anyway they have more packages being mailed than ever before I buy and sell online and am at the PO all the time to wait in line for 5 to 10 minutes in my tiny town when i was in St. Louis & SE MO I have waited in line for 30 minutes or more. the Gov will find a way to loose money no matter what .... that is their job isn't it ????
