This thread might also be of interest to you, HarryT.
I've purchased books from the UK Amazon in the past that they've been only too happy to ship here, perhaps the US Amazon would ship there, if it's worth the shipping cost to you.
It was very amusing to me to be able to purchase, receive and read Anne McCaffrey's
The Skies of Pern a full month before it even released here in the US. As an added bonus I like the UK cover art better than the US version too.
