If you like to read by the pool or at the beach, the 2021 Kindle Paperwhite remains one of the best e-readers available despite its age. That’s because, unlike Amazon's latest entry-level Kindle, the last-gen Paperwhite is waterproof.

Now through June 14th (or while supplies last), it’s on sale at Woot for $99.99, which is $40 off its original price. The offer includes 16GB of storage and a 90-day Woot warranty. This makes the old Paperwhite cheaper than Amazon's entry-level Kindle.

The 2021 e-reader offers both a large, 6.8-inch display and water resistance for under $100. It features a sharp 300ppi display and an adjustable warm front light which makes reading at night more comfortable. Battery life is also excellent, often allowing you to eke out months of use on a single charge before you need to top it off via USB-C.

Unless those upgrades matter to you, the older model remains a terrific value. The 2021 model is still snappy enough for most uses, and its 6.8-inch display remains spacious, especially compared to the base Kindle.
