I actually use the postal service now at most about once every other month.
IF I need to ship something, I take it to either a Postal Center USA(private company) or a Fed Ex office or UPS.
I certainly do not trust the USPS to ship anything important. They are an incompetent company.
The need for the USPS has gone the way of the buggy whip.
I don’t use the post office much. I bought 500 forever stamps 2 years ago and used 5 so far. I figure I’ll still have them when stamps are 5 dollars.
