As of Feb. 20, get the Amazon Kindle Paperwhite Kids for $139.99, down from its usual price of $179.99. That's $40 off and a discount of 22%. This discount currently applies to the Cyber City and Starfish covers that come with the unit.

That being said, a Kindle is a fairly expensive purchase. Amazon doesn't have deals on Kindle devices very often, but when it does, it's usually a good time to pick one up for a little bit less. Right now, Amazon is dropping the price of the Kindle Paperwhite as part of its Presidents' Day and Valentine's Day sales.

Amazon’s latest Kindle Paperwhite features a larger seven-inch display and noticeably faster performance. It also boasts longer battery life than the previous model, retains IPX8 waterproofing, and includes a USB-C port.
