GET DOUBLE KINDLE POINTS: As of Jan. 17, get double Kindle Points for each Kindle purchase, today only.

Are you a voracious reader? Looking to get paid back for some of the money you spend on Kindle books? Amazon’s Kindle Rewards program lets you earn points per dollar spent on Kindle e-books, and print books as well. You can redeem earned points for rewards and discounts (to buy even more books)/. And today, you can stock up on Kindle books and earn more points right now.

As of Jan. 17, you can earn double points on all the Kindle books you purchase today as part of the Kindle Rewards program. Between 12:00 a.m. PT and 11:50 p.m. PT, you can shop ’til you drop and get six points per dollar you spend on Kindle title, and one point per dollar you spend on print books.

The rewards you can earn through this program can net you cash for more books. You get $3 for every 300 points you earn, and for a limited time you can choose to redeem 300 points on your next Kindle purchase for $3 off.

It might not seem like a lot, but if you’re buying Kindle books anyway, you may as well earn a little cash back on each purchase. Even the smallest of discount can mean a very affordable Kindle book, since there are some titles on sale for as low as 99 cents. You can fill your device with tons of reading material just by splurging on some of the books you’ve had your eye on.

This deal is only going on today, so if you have some books in mind you still need to buy, go ahead and snag them. Those points aren’t going to earn themselves.
