USPS/UPS on it's worst day is still mile sbetter than the Autralian Postal service. I had a bow posted to me oncewith Aust Post and it was well packed, however some idiot had slammed the tip of the box in a car door by the looks of it and the bow was ruined. I complained and they fobbed me off saying that the bow was incorrectly packaged (untrue). Another time, I had a package with camo clothes, predator callers and all manner of goodies left on my 9 month old pups dog bed outside. Of course, pup thought it was all for her and demolished the package and contents forthwith. Same response from Australia Post again when I filed a complaint...
I have had many packages posted to me from the United States via USPS and UPS, never had a problem, items arrived faster than if I was to have something posted from within Australia.
