I use downpour.com for drm-free audiobooks. They let you straight up download the mb4 files haha it’s awesome.

It’s such a win-win b/c I get to buy audiobooks drm-free and I get to avoid supporting audible which has terrible business practices such as locking authors in exclusive deals.

Also thanks for the ebooks.com recommendation! I was reading this thread specifically to see if anyone knew of a good place online to buy drm-free ebooks :)
