“I was disgusted, but what could I do?”
I agree. But as to what? UPS, FedEx, DHL...
About the only thing I’ll ever send USPS are Christmas cards. I conduct all of my bill payments online.
While most businesses and individuals were adapting to electronic commerce the USPS kept sticking to the Pony Express method and continually raising their rates at the same time.
What did they think was going to happen?
