Have you tried buying something from the US? not to mention you usually lose any warranty on it, you generally get slapped with VAT, import duty and handling fees and often it works out more expensive in the end than cheaper.
Yep. Ive had a number of cards from the US and never been charged anything.
Shipping last time was $40 for two cards IIRC.
It worked out at a very decent price and the warranty is much better than what same company offers in Europe. 3 years and includes modifications to the card like fitting a water block or flashing the BIOS.
Oh, and I had the cards before the UK release.
Edit: I have had one card take three weeks to arrive.
