Amazon's October Prime Day deal brings the last-gen Kindle Paperwhite Signature Edition to $169.99, a 30 percent cut from its original $249.99 price. The discount applies at Amazon, Best Buy, and Target, making the premium e-reader more accessible than the current-generation model, which retails for $50 more.

The 2024 Signature Edition keeps the same 300ppi display, auto-adjusting front light, and waterproof design as the newer version. Its main advantages over the base Paperwhite are double the storage (32GB), wireless charging, and an ad-free lockscreen — features that typically justify the higher price.

The newer Kindle Paperwhite opens books 30 percent faster and is a millimeter thinner, but those improvements come at a significant premium. For most readers, the discounted Signature Edition offers nearly the same experience at a substantially lower cost, making it the stronger value during this sales event.
