Another source of free audiobooks is LibriVox which is building (i.e. recording) a catalog of free & public domain audiobooks. It is all volunteer work so I’m sure there is varying quality, but the few I have listened to have been quite good. However, the catalog is limited to works out of copyright (or under an appropriately permissive license), so newer material is rare, but many of the “classics” are there.
Audiobooks can be free if you get CDs from a library. (Then if you want, burn them onto your computer.) Also they may be available online as torrents.
