Audible Audiobook Membership

Audiobooks from Audible are normally quite expensive, as an Audible Listener, you can get one book (or lecture) for $15 or 2 books for $22 and cheaper annually. And you can find many offer codes (especially from podcasts) to get your first book free. Note that you can turn on and off your subscription to get credits at this price. At this point, I just buy an annual platinum membership because I buy so many books.
