Why is Dynaudio so much cheaper in Europe?

I've been looking at some store sites for European Hi-Fi stores, and I'm finding that even after shipping, and duties, I would be saving a few thousand dollars on anything in the Dynaudio line. In fact, with the Dynaudio 380's I'm interested it, I would be saving about $3,000, which is huge. My question is two-fold: 1. Why are they so much cheaper in Europe? 2. Is there anything to beware of when purchasing speakers from the EU and having them shipped to the US?
