What is the difference between the US and the eurpean Version of Parallels

[piebook]

Good morning all together,
yesterday, I saw an offer about Parallels for Mac, the prices differs a lot between an european and an US version of Parallels. Normaly the european versions are more expensive than the original US versions, the same like the Apple . Now I'm wondering why it isn't ? Are there any suggestions ?

But you can download the product, and pay by credit card. So the same price as all the world can pay.
