Amazon's Spring Sale kicks off March 25, but the best Audible deal of the year has already gone live. Starting today and running through April 30, you can sign up for three months of Audible Premium Plus for just $0.99 per month.

As a additional subscription perk, you get a free audiobook of your choice for each of those three months and you get to keep them indefinitely.Both new and currently expired Audible customers are eligibleAnyone who doesn't currently have an active Audible membership should be eligible. That includes new subscribers as well as existing members whose subscriptions have since expired. There's always a small your-mileage-may-vary disclaimer with these types of promotions, but fortunately it's easy to check if you qualify: log into your account, and if you see the $0.99/mo banner right on Amazon's Audible page then you're eligible for this promotion.3 Months of Audible Premium Plus for $0.99 per MonthNon-Current Subscribers Only3 Months of Audible Premium Plus for $0.99 Per MonthAudible is a subscription service that gives you access to hundreds of thousands of the best audiobooks without ever having to purchase them. There are two paid membership plans: the lower tier Audible Plus ($7.95/mo) and the higher tier Audible Premium Plus ($14.95/mo). The biggest difference between the two is the size of the audiobook library. Whereas Audible Plus only lets you listen to a selection of about 10,000 audiobooks, the Audible Premium Plus plan gives you access to a whopping 500,000 audiobooks. These include all-time classics like Frank Herbert's Dune, Harry Potter, Game of Thrones (A Song of Ice and Fire), The Witcher, The Sandman Series,and The Lord of the Rings.Although the seriously expanded library is the main draw of the Audible Premium Plus membership, there are some other nice perks as well. Every month Premium Plus members get to pick one audiobook to keep in their library indefinitely, even after the membership expires. Also, Premium Plus members can get 30% off any additional audiobooks they wish to purchase in addition to exclusive limited-time discounts.If you were already planning to purchase a couple of audiobooks, then it makes more sense to pay less than $3 to get three audiobooks you get to keep indefinitely and enjoy all the benefits of Audible Premium Plus for three months.
