Maybe I am missing something? Why would you use United States Postal Service to ship something between 2 foreign counties, Austria to Australia? No offense to mail couriers but they're a bunch of divas around my parts. They won't even get out of their truck to deliver my mail if the mail box is blocked by a car. And this isn't a new habit they have been like that the entire 7 yrs I've lived at this address. USPS problems are much deeper than just the "Higher level".
They've had problems for years. I bought a guitar via eBay about 10 yrs that was shipped by USPS. Came from the south east (Virginia or Kentucky) to MN. It took 21 days. Why?? I can walk that far in 21 days. Maybe they should of never started shipping large packages. Moral of the story don't call a plumper to fix your car.
