Kindles are perfect summer vacation companions, offering everything you’d need in a top-notch e-reader.

We’re nearing the end of Prime Day, so many of the deals below will no longer apply tomorrow morning. Right now, the best deals on Kindles are on the Kindle Scribe models. Amazon has taken a little off of other Kindle models but has substantially discounted the Kindle Scribe with discounts starting at $105 and going up to $175 on select models More
