Libro.fm is like Audible except that your purchase goes toward an independent bookstore (you can choose your local bookstore or another one that you love!) instead of Amazon.
If you refer a friend who signs up you can earn an audiobook for free!
Alternatively, you can get 2 audiobooks of your choice for $14.99 here!
(And if you need some suggestions for audiobooks, here are my favorites for adults and here are my favorites for the whole family!)
