I IM'ed you almost a month ago, should I stop waiting?

I'm still trying to find out why the cost of downloading Poser 6 for an Australian is so much more expensive than for an American.

I know our Free Trade Agreement means there are no additional duties or taxes, and there is no shipping cost, so the cost should be the same as a US customer. Yet the store only gives me the option of paying as a European customer, at an inflated cost.
