How does Audible work? I see you pay like 7.95 a month for credits. I take it one book is one credit? Is this an actual copy of the book, or will it only work though the Audible website? What I mean is, does the book become yours even if you cancel your subscription, or do you loose all your books?
http://www.recordedbooks.com. Click on consumer. You can either rent CD format or join the RBU book club. It's like a netflix for but audio books. The other option you have is to go look at your local library. More likely that not they will have the audio books there and may also offer a digital downloads.
Hey these are great resources! http://librivox.org/ has public domain books for free. While general reading might not be found here, if you need books for college classes and would rather listen instead, its a great place to find them.
