There’s a pretty easy rule to buying a Kindle: Wait for a sale. Amazon’s Prime Day Kindle deals, which happen every summer and fall, plus other sale events like Black Friday, always offer the best prices. While Amazon’s summer Prime Days were in July in previous years, this year they arrived early, in June, and will run for almost a full week from June 23 until June 26.

Any day during that sale is a great one to claim your own new Kindle e-reader from Amazon. The on-sale Kindles usually don’t sell out, but if there’s a specific color or storage size you want, you might want to snap that up early in case that specific version does sell out for a little bit. So far, there are no Kindle Scribes planned to go on sale, but it would be nice to see options like the expensive Kindle Scribe Colorsoft available for cheaper. Here are the best Kindles that are on sale right now.

Best Prime Day Kindle Deals

If you want the best e-reader Amazon makes, it’s the Kindle Paperwhite. It has a 7-inch screen that’s illuminated by an adjustable warm front light, and a battery life that lasts up to 12 weeks. The screen is only black-and-white, but it’s got great contrast and snappy performance, and the sale price makes it a great deal. Both a Signature and a regular version are on sale, and the Signature adds an auto-adjusting front light and wireless charging.
