btw, amazon.com allows you to enter a different country address if you need a book from outside your region. They even have a handy prompt, along the lines of 'Moved recently? Change your address here!"
So according to them, I live on Park Ave, NYC, but they ship all my shit to Tokyo. Everyone is happy with that arrangement

Now, that doesn't mean it's perfect, as I would like to buy books from the UK as well. The problem is that the Kindle is linked to one account, so I can't just switch to my amazon.co.uk account. But so far, I've been able to get everything I want as long as it's on Kindle somewhere.
