Not sure if this has been mentioned but Amazon are currently doing a nice deal on all books: 30% off until 1 December. There is a catch - only one order per account and a maximum discount of $10 so effectively its 30% off on books under around $33 and $10 off books over this price. So not quite as good as the headline but still a nice $10 saving and a good excuse to buy one of those photobooks you haven't got round to yet. I just used it to order Martin Parr's The Non-Conformists. You can find all the details here.
