in case anyone is interested, I just bought a book which was only available in the US (ie not through amazon.co.uk or even in europe via amazon.com)
just added the address of a Hotel in New York to my account, fired up the amazon store on the kindle, paid in dollars using my usual 1-click card thingy, book arrived seconds later.
I have since changed my address back.
seemed to work perfectly, dunno if there could be any comeback, presumably they cannot deauthorise a book because you appear to be in a different country..
