Amazon embarrasing itself

I've complained before about Amazon's book recommendations that I get via email. But today's recommendation just totally baffles me.

Yesterday (or the day before, I forget) I pre-ordered "The Children of Hurin", the new Tolkien book from Amazon.co.uk. Today I get an email recommending this book to me and telling me what a great deal I can make if I pre-order it from Amazon. Well, doh!
