Amazon
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.
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.
Your Prime Big Deal Days FAQs, answered
What is Prime Big Deal Days?
This annual Amazon sale — which we like to call October Prime Day — is similar to the well-known July event: it’s a two-day blow out shopping event with deep discounts on bestsellers and everyday essentials. But the timing of this sale makes all the difference; shoppers can also score pre-Black Friday deals on top-rated toys and sell-out-risk gifts before the holiday rush.
How long does Prime Big Deal Days last?
Amazon’s fall Prime Day event only lasts two days. This sale starts on Tuesday October 7 at 12:01 a.m. PT and runs through Wednesday October 8 at 11:59 p.m. PT.
When does Prime Big Deal Days end?
Prime Big Deal Days 2025 ends on Wednesday October 8 at 11:59 p.m. PT, so east-coasters have until about 3 a.m. on October 9 their time to shop the deals.
Do you have to be an Amazon Prime member to shop?
Prime Big Deal Days is a member-exclusive sale event. Interested shoppers can grab a 30-day free trial to try Prime, and its many benefits, with no strings attached.
Prime Day vs. Prime Big Deal Days: What’s the difference?
Already familiar with July Prime Day? Then you’ll love Amazon’s fall version! Like its summer spectacular sale, Amazon’s Prime Big Deal Days offers major discounts for 48 hours, but with a bigger focus on holiday gifts, toys and tech to shop ahead of Black Friday and Cyber Monday.
What are the best deals?
From reporting on Amazon sales for years, we can tell you for certain that October Prime Day is the ideal period to stock up on household essentials, score great deals on gift-worthy items and toys, take advantage of Black Friday-level discounts on tech and appliances, refill your skincare empties, and comb through the massive catalog of Amazon best-sellers.
Is it worth it?
We certainly think so! October Prime Day is a great chance to score Black Friday-worthy deals on thousands of best-sellers, including everything from big-ticket tech to Post reader-favorite trash bags. Our team diligently sorts through all the offers to find you the very best items to grab on sale.
When is the next Prime Day?
Already wondering when Amazon’s next Prime Day is? Prime Day takes place in July each year, so it’s safe to assume it will take place in mid-July 2026 — similar to previous years. Can’t wait to shop more Amazon deals? Look out for Amazon’s Black Friday sales to kick off the holiday season in November.
