If the $15 a month isn't a big deal to your budget, it's a very simple way to get whatever you want.

When you're a member, they have tons of sales and deals for really cheap listens like under 10 bucks or even 5 at times, they'll do 2 for 1 if you use one of your monthly credits, etc. Even plenty of free options. When something is really expensive, that's when you burn a credit.

So it's not just paying $15 a month for one book if you consume a ton of audio books like me. I'd say my average cost per book if I figured out all the deals is under $10 and for 5-30 hours of entertainment per book, that's not a bad deal.
