BookFunnel - Is Gumroad a Good Option?

Selling an e-book on Gumroad is just as easy as having your book on Amazon, except you get all of the advantages of selling directly. The author can alternatively also offer DRM-free MP3s - that's for the techier crowd. Most readers are listening to audiobooks within our app, they already have our app installed. And we built our audio app to work pretty much as seamlessly as you would expect from Audible.
