The Post Office blows!

I work in a shipping/receving department. We use UPS, Fed EX, Reddaway, EPX (before they went under), Danza, ect. UPS has a 6 foot drop rule, If it wont survive a 6 foot drop dont use ups, If it is longer than 2 feet, dont use ups. Fed Ex isnt too bad just as long as your murchandise stays off one of their main docks that is when some jackass decides to run into a pallet of glass with his forklift or knock it over and then igore the broken sound. I have been hearing good things about DHL but I haven't delt with them yet.
I wouldn't ship anything bigger than a shoebox with USPS.
