I do not trust the USPS to do anything other than steal packages and transport/deliver fake ballots for the Democrat Party. I just had an electronic controller disappear and yet it was input into their computers as delivered. We have a small and very safe neighborhood. The company from which I bought the controller accused me of trying to get a free item but shipped me an other anyway.
My last problem with UPS was earlier this year I made a purchase of some ammo from a retailer in my state. It showed up a day late and the box was torn open and re-taped. when I opened the box it had only 100 rounds of the 500 I had ordered. When I called the store they were concerned and told me this was not the first time this year. They immediately sent me 400 rounds.
Seems like USPS can be radically different in different parts of the U.S.A.
Service is totally dependent on the character of the people involved.
