Get Kindle Unlimited free for 3 months with this early Prime Day deal

Amazon’s Kindle Unlimited deal is finally back ahead of the October Prime Day sale: Right now, you can sign up to get Kindle Unlimited totally free for your first three months — down from the usual price of $11.99 a month. If you own a Kindle and haven’t tried Unlimited yet, I highly recommend taking advantage of this deal.

Kindle Unlimited gives you access to a library of over 5 million digital books and thousands of audiobooks, including recent bestsellers, popular series, classics, and more. 

After the three-month promotional period is over, you will be automatically charged the full $11.99 a month plus taxes — but the good news is, you can cancel any time before you get charged, so it really is a free offer.

This deal is open to new Kindle Unlimited readers and select returning ones. (For example, my colleague can see the offer for 3 free months, but because I recently had another free offer and then canceled, I don’t have access to this one through my account. I hope to sign up again when there’s another offer, because I really love the service.)

Kindle Unlimited includes bestsellers like The Fourth Wing and The Hunger Games series, and novels from popular authors like Colleen Hoover and Frieda McFadden, among many others.

We’re also expecting to see price drops on Kindle devices during October Prime Day next week, so keep an eye on our best deals page.

Don’t miss this deal to get Kindle Unlimited for three months at no cost.

How I rated this deal 

Even though this discount is only for 3 months, it saves you $36, which is pretty great. It’s also a nice, low-risk way to test out Kindle Unlimited for a longer period of time than the usual 30-day free trial and see if paying the full price is worth it for you. That’s why I’d rate this deal a 5/5.

When will this deal expire?

This deal runs through Amazon’s Prime Big Deal Days sale, which ends Oct. 7.
