Last chance Prime Day deals: Get up to 36 percent off Kindles and ereaders

Engadget has been covering Amazon Prime Day sales for years — and we've noticed something about Kindle deals. While some discounts may linger after the sale is over, the ereader deals tend to expire when the event. So if you've been considering a new Kindle, you may want to buy it now. Prime Day ends at midnight West Coast time, so you've only got bit more time. Every Kindle model Amazon makes is on sale — and we've reviewed almost all of them. If you need some more info before you buy, feel free to read our thoughts on the Paperwhite, the Colorsoft, the Scribe and the basic Kindle. Here are the best Prime Day Kindle deals.

Amazon Kindle for $85 ($25 off with Prime): The base model Kindle is our recommendation for the best budget ereader. Even when it’s not on sale, it’s the most affordable e-book device from a major manufacturer. It’s compact and durable making it easy to carry. It doesn’t have warm LEDs and it’s not waterproof but it’s the most affordable way to access Amazon’s vast e-book ecosystem.

Kindle case (fabric) for $24 (25 percent off with Prime): If you want to protect your new ereader, you can grab this case while it's 25 percent off. Note that only the blue and pink versions are $24, the black and matcha versions are $2 more expensive.

Kindle Colorsoft for $180 ($100 off with Prime): Amazon didn’t introduce color to its ereader lineup until early this year — long after Kobo and Boox. The list price of $280 makes it more expensive than other color display ereaders, but this discount helps with that. We appreciate the fast page turns, pinch to zoom feature and auto-adjusting warm front light.

Kindle Scribe 2 for $260 ($140 off with Prime): If you want a Kindle that lets you write as well as read, this is the one to get. We gave the Kindle Scribe 2 a score of 86 in our review and it’s our pick for the best e-reader E Ink tablet. It has a smooth reading and writing experience with low latency. It also lets you create multiple notebooks, add pages and change the templates easily.

Kindle Paperwhite for $125 ($35 off with Prime): The Paperwhite is an elevated version of the Kindle, with a larger, seven-inch, flush-front screen and an adjustable warm front light. A faster processor gives it quicker page turns than its predecessor and the device itself is waterproof.

Kindle Paperwhite Signature Edition for $150 ($50 off with Prime): The Signature Edition adds few more premium features to the Kindle Paperwhite with wireless charging, an auto-adjusting front light and more storage (32GB). We gave it an 85 in our review praising the premium build, remarkably clear text and fast page turns. We just wish the power button wasn’t on the bottom.

Kindle Kids for $95 ($35 off with Prime): The Kindle Kids edition is the same hardware as the standard Kindle, but you get a few added perks that are fitting for younger users. To start, a case comes standard. The warranty is extended to two years. And the purchase price includes a six month subscription to Amazon Kids+ for thousands of kid-friendly ebooks and more.

Kindle Paperwhite Kids for $130 ($50 off with Prime): Again, the kids version is the same as the Paperwhite but with a cover, extended warranty and access to Amazon Kids+ for six months. Just remember to cancel at the end of the trial or keep it and pay $6 per month.

Boox Palma 2 for $270 ($30 off): This smartphone-shaped device is a delight. It’s built on Android and can run just about any app you can download from the Play Store — just don’t expect it to play video or graphics-intensive games. This is an E Ink screen, after all. But it’s perfect for reading books and running simple apps in a more eye-friendly format.
