Amazon’s second Prime Day of the year is here and a few of the deals extend to Kindle ereaders. Unfortunately, the standard Kindle is currently out of stock, as are a few other models. That could be a hint that a new Kindle device is on the horizon, but we don't know anything for certain yet on that front.

In our buying guide for ereaders, we acknowledge the fact that Amazon is the dominant force in this universe. But the even the most recent Kindle, the Kindle Scribe, is nearly two years old at this point. Now that Kindle rivals Kobo and Boox both have color models, one can only expect the same from Amazon soon. Still, unlike a tablet or a smartphone, Kindle readers are meant to do one thing well: display text on a distraction-free, easy-on-the-eyes screen. And all three of the models on sale do that quite well. Here are the best October Prime Day kindle deals (all three of them).

Amazon Kindles dominate the ereader market, and right now there are four models to choose from. Of course, a new Kindle is likely on the horizon — rumors suggest as much and the last entry in the lineup came over two years ago. But since ereaders aren't as tech-heavy as a tablet, the generational bump may not make as much difference. What you buy today should still serve its basic function —displaying crisp text — for years to come. Here are the best Prime Day Kindle deals.
