The Kindle Colorsoft Signature Edition is Amazon's first and only color e-reader, released this winter. It has a seven-inch screen, an ad-free lock screen, a speedy performance, and a waterproof build.

Thanks to Amazon’s Book Sale, the Colorsoft just got a whole lot more tempting. It has dropped from $280 to $225, which not only marks its lowest price yet but actually undercuts most other color e-readers out there. That’s 20% off, and the deal still stands even if you grab the free three-month Kindle Unlimited trial with it.

Amazon has sold Kindle ereaders for almost two decades but it wasn't until last year that it went beyond black and white. The Kindle Colorsoft Signature Edition came out in October and — despite a previous screen issue that seems fixed — it's a great product overall.
