TL;DR
- Prime members can currently claim three free months of Kindle Unlimited if they are not already a subscriber.
- Kindle Unlimited provides access to millions of titles and works on Kindle devices and the free Kindle app.
- The promo is part of the lead-up to this year’s Prime Big Deal Days beginning on October 7, 2025.
Amazon is already baiting book lovers ahead of its October Prime Big Deal Days. Right now, members can sign up for three months of Kindle Unlimited at no cost, running back a similar promo we saw ahead of Prime Day in July.
Normally $11.99 a month, Kindle Unlimited unlocks millions of ebook titles, plus audiobooks, comics, and magazines. With a subscription, users can borrow up to 20 titles at a time, which is ambitious even for the most committed of bedrotters. You also don’t need a Kindle to utilize Kindle Unlimited, since everything included works seamlessly in the free Kindle app on Android (or iOS). In other words, if you don’t have a Kindle, you can still sign up for the free period and read or listen on your phone or tablet.
