Amazon Prime members can get their first three months of Audible Premium Plus for free until July 31.

Amazon Prime Members can sign up to get a three-month trial of Audible Premium Plus, which means you’ll get one audiobook of your choice for free. Users will have full access to the Audible Plus catalog of Audible Originals, audiobooks, and podcasts. The promotion begins today and runs through July 31 and it works for former subscribers.

Kindle Unlimited gives you access to more than 4 million digital titles, including fiction, non-fiction, audiobooks, and magazines. It normally costs $11.99 per month, but during Prime Day, Prime members get three months free. I personally don't always read fast enough to justify the $11.99 a month, but I'll take three free months of it any day.
