Compare the prices for Adobe Photoshop, or Macromedia Dreamweaver, or Quark Express. This price difference happens with almost all software. It's because of the cost of setting up distribution in different countries, and setting up support options in those countries. The US has a HUGE potential customer base and potential for very large quantity of sales so can have lower per unit distribution and support costs and hence lower prices. On the other hand in the US we tend to pay a lot more for European imports.
