We could never work out how I could buy an item from China for 50 cents and have Australia post deliver it to my door when I think the min postage cost for a letter here is $1. Something had to happen but it will probably spell the end of what I have been doing for the last few years
It is because they make it up off us small users.
I similar problems even our First class is currently 50 cents for ounce domestic yet I get packages from China for a just few dollars. I even in bound package stateside that are at least half of what it takes me to send them out.
I recently had a new UC to fail and needed to send it back to Canada for warranty repairs. They want me to send via US mail back but it was going to cost me $89 one way. Then I called the Canadian company and they sold me a round trip shipping label for $35. This I was willing to pay to have a $200 UC repaired.
These crazy shipping rates just don't end either. I ordered a spindle out California and was charged $6 to get it but was charged $14 to ship it back. The worst of it was the company I order from charged me a 30% restocking fee for a defective item so I ended wasting that $35.00.
