I used to run a business with shipping and can think of one lost package out of thousands of items with USPS. I don't think people give them enough credit. Fed Ex and UPS are way worse. Fed Ex left my wife's engagement ring and $500 Steelers playoff tickets on the front porch when there was a signature required. The tickets were laying in the snow in paper mailer. I once watched a UPS driver load up a dolly passed his head of fragile item boxes only to have them fall over and then dumb sh*t did it again and they all fell over again. I thought I was on one of those hidden camera shows.
