It’s easy money all the same. You know how Amazon’s affiliate program pays you a little dough every time someone orders a product through your link (via your website, Facebook page, Twitter account, etc.)? I have an affiliate program for Liberty Classroom, except I pay you $30 every time someone joins through your link. And the first time you bring in a subscriber through your link, I also send you two of my books, signed.
Sign up here, and watch the dough come rolling in.
