I remember when Steam did this back in the day (not sure if it still happens today) and it was a total shame. Lots of people using proxies to get US pricing on the other side of the pond. Now, I don't really know how the whole taxing thing moves about, but, are foreign customers forced to pay taxes for these kinds of products since they're considered 'imported'? Or maybe, do companies feel they should get more money to keep operating abroad? I'm just trying to look for possible explanations, but we all know this is just a cheeky, greedy play from these companies.
