USPS is on a steady descent into oblivion, I think. Customer service is non-existent, and packages take longer and longer to wind their way through the roundabout circuit. I submitted a change of address online and had to pay one dollar and five cents for the privilege of doing it online. What did USPS do? They just started returning all of my mail back to sender. I've tried repeatedly to have this rectified, but all I ever get is a promise that someone will call me at some point. The calls never come.
Anymore, I pay the extra and ship via FedEx or UPS. They're at least professional and efficient.
