Here's the problem with Audible... They *really* want you to use their subscription service. If you want to just buy an audiobook get ready for an obtuse, infuriating and unnecessarily complicated process. I was asked to subscribe no less than 5 times before I was able to complete a single purchase of a single audiobook. The app works fine. Not a really great interface since you can't listen to a book without again being asked several times to please subscribe.
