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.

Kindle Unlimited subscription
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.
How does Kindle Unlimited work?
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.
What books are included in Kindle Unlimited?
Here are just a few of the books you can read for free with Kindle Unlimited.
