Amazon Prime Big Deal Days, a.k.a. October Prime Day, is almost, and if you thought the deals start and end with physical products, think again.

The sales event begins tomorrow, Oct. 7, and runs through Oct. 8, and right now, a new offer on Kindle Unlimited is available.

Right now, Amazon Prime members can get three months of Kindle Unlimited for free. The subscription is normally priced at $11.99/month, so this is a pretty sweet deal if you ask us.

Most Prime Day deals, including the Audible deal and this Kindle Unlimited offer, are only for Amazon Prime subscribers.

If you aren’t one already, you’ll need to be anyway to shop the rest of the sales, and who can resist a free trial? A Prime membership costs $14.99/month or $139/year, and in addition to access to exclusive deals, you’ll gain access to free books on Prime Reading, the Prime Video streaming service, and so much more.

Plus, if you’re between the ages 18-24, you qualify Prime Student/Prime for Young Adults membership, which is just $7.49/month after an initial six-month period at $0.00/month.

Kindle Unlimited’s library is made up of over four million titles, per Amazon, and we’ve found that there seems to be a particular emphasis on romance novels and thrillers.

Kindle Unlimited’s catalog changes often, and once you borrow a book, it stays in your library until you return it — even if that book is no longer available to borrow on Kindle Unlimited. We recommend borrowing books as soon as you see them, even if you don’t plan on reading them right away, because you never know when they might disappear from the service.

Kindle Unlimited is a subscription-based service by Amazon that gives readers access to over 4 million e-book titles for one low monthly price. If you read just two KU books a month, the subscription pays for itself.

Not unlike a library, subscribers can borrow up to 20 books at a time. There’s also access to select audiobooks and popular magazines.

Here are just a few of the books you can read for free with Kindle Unlimited.

Prime Day and all its amazing discounts are exclusively available to Prime members. However interested shoppers can grab a 30-day free trial to try Prime, and its many benefits with no strings attached, and gain access to exclusive deals and the convenience of fast, free shipping.
