I know it's silly, but I really did want it, so even though the pound is at record highs against the dollar, I went ahead and ordered the UK edition of Harry Potter from amazon UK. It'll come air mail, which I expect means about a week after the US edition. Thankfully, unlike some of my friends, I'm not particularly concerned when I read it.
For those of you familiar with the UK's habit of publishing an 'adult edition' of the Harry Potter books, don't worry - I ordered the kids' version. Both UK editions have different covers than the American edition.
