If you have time on your hands to listen in the car, at your home, while you exercise, or instead of watching tv, here are some places to pick up free and cheap audiobooks.
You can check out a handful at Noisetrade
Here is the Christmas Carol
Here is one on leadership from Christianaudio.com (never read it though)
These are $.99 but normally pretty fun to listen to
