Woot has an audiobook deal today... This set (and importantly the narrators and readings) get great reviews on Amazon where it sells for $80.
Better yet, the creators encourage sharing the audio files!
Yes with dozens of hours u could get audios for many of these for free but convenience has a value....
"LENGTH = ALL UNABRIDGED The AudioBooks are unabridged and vary in length. There are many short stories as well as longer epics. In all there is roughly 2,000hours worth of listening. So at say 1 hours a day it should last close to 6 years. SHARING Lastly we encourage sharing these are not protected or restricted in any way. By all means, feel free share with friends and family. The more the merrier. "
