I've just spent 6 weeks getting a global shipping calculator setup for my pre-launch business. In the end I had to enlist the help of the developer himself after my website developer couldn't work it out nor a consultant I hired and nor could I. ! It's no mean feat that's for sure so he has my sympathies for that! It takes over 8 seconds for all the rules to load when loading the shipping plugin! there's over 500 different rules/categories!Hope he gets his shipping calculator fixed. I did a re-ship for one of our international members. He bought 1 card protector and had it shipped to me. Shipping was over $13!
I re-shipped to Australia for about half that.
