For the first day of the two-day event that is Prime Big Deal Days, Amazon has marked down tons of e-books, from self help to fiction and children's books, for prices as low as $1.99.

During Amazon Prime Big Deals Day on October 8 and 9, you can save big on a few popular Kindle models and thousands of e-books. Below, we’ve rounded up our favorite Kindles and novels to stock up on—but the sales event ends tomorrow, so we recommend adding these to your cart sooner (rather than later).

If you want a Kindle Paperwhite without ads, you’d typically have to pay $169.99 for the privilege. Thankfully, though, the Kindle Paperwhite Kids offers a way around that, making it a great e-reader for the whole family.
