USPS is awful. No accountability. Their prices are also now through the roof. Recently, I finished a book and wanted to send it to my sister in ABQ. Had to go to the post office anyway so took the book in a box. It was going to be something like $25 to mail the book at the cheapest possible rate. The stinking thing only cost $15 delivered from Amazon! Needless to say, I did not mail the book but just bought another copy for her.
UPS might actually be worse. If, for whatever reason, the sender required signature for delivery, and you happen to not sit at home 24/7 waiting for the UPS guy, youβre screwed. There is no way to get ahold of them. You can try their phone number, but you have to input the tracking number by voice (not phone number pad), and does not recognize the numbers. I tried this with three different people (had 3 different friends try to speak the number), using all 4 chances you get in a phone call, and never was able to get past that dead trap in the help loop. Package got returned.
