It has been ten years since Amazon first introduced its dedicated E-book reader, the Amazon Kindle. To celebrate its anniversary, Amazon has discounted a number of its E-reader products, as well as the subscription price to its Kindle Unlimited E-book service.

The Kindles are regarded by many as the best devices for E-reading, and Amazon’s focus on them makes a lot of sense given that the retailer began its life as an online bookstore. You’ve got until Wednesday night to get in on these deals, which you can find at the links below, while you have until Saturday to pick up a Fire tablet as part of a Halloween sale.
