All of our role playing games and RPG sourcebooks (but not fiction at this time) come with the Free PDF Guarantee.
CONSUMERS: You can get the PDF from us free by sending a proof of purchase to email@example.com. We’re pretty informal about what kind of proof. Usually a photo of the book with the receipt works great. Or maybe post a photo on Twitter or something of you holding the book looking happy. Free advertising for us, free PDF for you.
RETAILERS: A customer who buys the book in print at a retailer can get the PDF free. You can even offer the PDF download immediately at the point of sale by signing up with Bits and Mortar.
