FREE eBook to accompany PAID Print book
There is a print book on Amazon, with an ISBN number, which is available for purchasing. I am looking to make a FREE eBook that accompanies the print book. The eBook must be accessed AFTER the print book has been purchased. Is that possible through Lulu? How can I ensure that the process is 1. Paid book purchased first, 2. FREE eBook after purchase.
Your assistance will be greatly appreciated.
