If you're still in the market for a new ereader, Amazon is holding a belated back-to-school sale on the basic Kindle.
Buy two Kindles on Amazon.com, enter the code TWOPACK40 at checkout, and Amazon will take $40 off the order. For the ad-subsidized model this is basically a buy one get one half off sale, although the ad-free model costs $20 more.
Speaking of which, if you do go for this deal and you want the white Kindle, you'll need to either pay extra for the ad-free unit or wait a month. While the black model is in stock, the white option for the Kindle is back-ordered until 18 October.
