I would have, but didn't want to transfer my account to the UK Kindle store (although you can freely switch back and forth, at least for now). These were the first listings I'd seen that would not let you purchase them in the US Amazon store with a UK address (Amazon.com would say they were not available to those in the UK, while Amazon.co.uk would tell you that only UK customers could purchase, until it suddenly decided that I could transfer my account and get them).
In any case, I can't wait until they are released, so will have to find substitutes...
Those who are having new children this year, though, should find that they come in handy when they start prepping them for college entrance exams.
