UPS beats up, stomps, or drives over my boxes ... because they always come out looking pretty trashed. one time i got an empty envelope that looked like it had literally been driven over. there were tire marks (no not that kind) on it.
also UPS leaves expensive packages on my doorstep. they left a digital camera there once. my housemate (LAWRENCE WOO) had a couple of laptops left on on doorstep also. this is NOT good since we live on a street almost right next to campus. everyone and their mother walks by our house.
i had a lot of faith in USPS until recently, when someone from half.com sent me the rocky dvd set. granted that the person did a really crappy job packaging it (larger box, with just crumpled newspaper padding), the box looked like it had been speared by something. one entire corner of the box was dented way in and the dvd box case was bent in. nothing major that broke the dvds and nothing too major to ask for a return, but annoying nonetheless.
fedex ground ... they're okay. i think they've stomped on a couple things too.
have had great experience with airborne express. heard they're expensive though. i did all my Dell RMA stuff through them though (paid for by Dell).
my final conclusion? if money were not an issue, airborne express. however, i do USPS 'cause its convenient.
