Amazon Prime members can get three audiobooks of their choosing for free right now as part of the retailer’s early Prime Day 2025 sale. Technically, you’re getting a free 3-month membership to Audible Premium Plus ($45 value), but that membership includes Audible credits that can be used on any book in Audible’s massive catalog, including new releases and preorders. This offer is only available to Prime members and expires July 31.
The Audible signup deal is for new subscribers, but if it has been a while since you had an Audible subscription, you should check to see if you’re eligible. The same goes for the Kindle Unlimited Prime Day promotion, which also lets new members get their first three months free.
How to get three free audiobooks at Audible

Audible Premium has thousands of audiobooks, podcasts, and original productions for subscribers to listen to whenever they want. The major perk of the Premium Plus tier is the aforementioned Audible credits. Each month, Audible adds one credit to your account that can be traded for any item in the Premium Plus catalog. Members can also purchase additional Audible credits for $15 each, and it’s a good strategy to use since audiobook prices are often higher than $15.
Best of all, buying books with credits is the same as paying cash; you get to keep audiobooks purchased with Audible credits even if you cancel your subscription. That said, you will lose any unused credits when you cancel, so make sure you spend all three before unsubscribe.
After the 3-month free trial, you will be charged $15/month going forward unless you cancel before your renewal date. As an alternative to canceling, you could switch to Audible Premium, the $8/month subscription tier that includes the aforementioned catalog of listenable content; you just won’t get an Audible Credit each month.

The promotion is a nice opportunity to start or catch up on a new series such as Pierce Brown’s Red Rising, Frank Herbert’s Dune, or Brandon Sanderson’s The Stormlight Archives. There are some book series that are often viewed by fans as better in audiobook format. For instance, Matt Dinniman’s best-selling LitRPG series Dungeon Crawler Carl is an Audible exclusive that is brilliantly narrated by Jeff Hays. For science fiction readers, Dennis Taylor’s hilarious Bobiverse series is an entertaining ride made even better with Ray Porter’s incredible narration.
Since Audible credits can be used to buy any book in the Premium Plus catalog, it’s not a bad idea to put them toward brand-new releases that likely have extremely long wait times at your local library. For example, you could get Sunrise on the Reaping, the latest novel in Suzanne Collins’ wildly popular Hunger Games series. Stephen King fans can pick up the excellent audiobook edition of Never Flinch, which released at the end of May. Fantasy readers should check out Joe Abercrombie’s The Devils, the first book in the best-selling author’s new epic fantasy series.

Kindle Unlimited: Amazon Prime Day 2025 Promotion

Amazon is also offering three months of Kindle Unlimited for free to Prime members. A Kindle Unlimited subscription unlocks instant access to over four million ebooks, including novels, comic books, manga, and more. You can borrow up to 20 ebooks at a time and swap them out as often as you’d like. Some Kindle Unlimited books also come with a free audiobook version that will automatically be added to your Audible collection.
How to get Amazon Prime at no cost
If you’re new to Amazon Prime, you can sign up for a 30-day Prime membership without spending a dime to take advantage of Prime Day deals, including the Audible and Kindle promotions. It’s also worth noting that students and anyone aged 18-24 can get a six-month trial at no cost. If you aren’t eligible for the trials, Amazon Prime’s standard membership costs $15/month or $7.49/month for the new Young Adult membership tier. So you can simply subscribe for one month and then shop all of Amazon’s Prime Day 2025 deals.
Amazon Prime Day 2025 officially kicks off on July 8 and runs through July 11.
