but about half the time Amazon ships with USPS they screw something up. With UPS it's only a very small amount of the time. The USPS is just so inept. This time I ordered a heavy package that the USPS labeled as tried to deliver but no one home before they even came by. Then they left a note that it's required to pick it up from the post office (can't ask for delivery). They do this crap all the time and not just to me. They just didn't want to deliver a large package.
