I do this with audiobooks, too, but consider libro.fm instead. Same pricing last I looked, and part of my monthly subscription goes towards my local bookseller.
That said, a +1 to Prologue from me. Fantastic app.
I'll check that out. Sometimes when I'm moving between an audiobook and my kindle I use the official Audible app (WhisperSync is pretty freaking cool) which is the main reason I've kept my Audible subscription. Though there as some books I have no plan to read+listen so I'll look into libro.fm!
You can get book credits with a monthly subscription, I think when I was doing that it was about as good a deal as audible. libro.fm also has the advantage of being DRM-free from the start
Oh, right, I do the subscription, so it's $15/mo for 1 audiobook, plus 30% off further purchases. I guess I don't "audio-read" that much, so that's a good deal for me. (I actually have credits saved up, which don't expire.)
That said, a +1 to Prologue from me. Fantastic app.
