CL (actually, Digital River) is collecting VAT, separately from the listed price.

The law changed recently (in 2003, I think). U.S. companies selling stuff in the EU are required be registered in at least one EU country, so they can collect VAT and turn it over. They can't really enforce it, and small companies probably aren't doing it. But any company that doesn't, and then wants to do business in the EU will face back taxes and fines.

I'm not a lawyer, and export/customs law is so complicated it's a specialty all its own. But this is what it says on the Dept. of Commerce Web site.
