Thanks for this, https://www.audiobooksnow.com/ also looks like a good option for DRM free audiobooks. I think people should definitely vote with their wallets here as there are alternatives. I can find almost everything I want on downpour (and possibly audiobooksnow) and the monthly fee is lower than what I was paying at audible.

The other big one is libro.fm, which I also think has the nicest website, for whatever that's worth. There's also Google Play, but they always seem to be more expensive.

I've been using a combination of these three sites (libro.fm, downpour.com, audiobooksnow.com) for many years now. Although I do occasionally need to hop back over to Audible for one of their exclusives, but not often.

Quick note about audiobooksnow.com, they do have a small number of DRM'd titles. Check for a "Downloadable" icon before buying!
