The company I work for uses Airborne/DHL and I've had no problem with them. Minor
issues, but that's to be expected. I'm happy with them and there's a station
nearby.
UPS sucks. They beat the shit out of packages. I've mentioned in previous threads
about crushed boxes I've got from them.
USPS is ok, but the post office nearby is always busy. Averages 12 people in line all the
time it seems. Getting through there is slow since the employees do not know what speed of
service is.
I'm happy to have discovered Fedex ground. Heck of a lot cheaper sending large/heavy
goods than USPS. I use it when sending out ebay goods.
