SAVE $35.97: Take advantage of three months of Kindle Unlimited at no cost, typically $11.99 each month.

Prime Day brings an array of attractive discounts, yet one of the most remarkable deals this year is entirely free, at least for the moment. Prime members can enjoy three months of Kindle Unlimited without any charge.

This special deal for Prime members is part of Amazon’s Prime Day celebration. It’s an excellent choice for getting through summer reading or delving into audiobooks for your upcoming road trip or daily commute.

Kindle Unlimited is Amazon’s digital membership service that provides access to more than 200,000 e-books, thousands of audiobooks, and trending magazines. Whether you enjoy thrillers, sci-fi, romance, biographies, or just want to explore People or Better Homes & Gardens, there’s a title for every reader.

Typically priced at $11.99 per month, this three-month trial offers a $36 value. Following the trial, it automatically renews at the standard rate, but you can cancel at any time during the trial to prevent charges.

If you let this pass, there’s no need to fret — Amazon regularly presents three months of Kindle Unlimited. Just put a reminder if you wish to opt-out once the trial is over.
