If I have a physical copy of the book, do I get a free digital copy as well and if so, how do I go about adding the digital copy to my account?
Hello Oliver, welcome to Demiplane!
The Demiplane platform is a separate entity from our various partners (like Marvel), and the digital titles on Demiplane are separate products from the physical books. Purchases of a physical book do not include a digital copy here on Demiplane, or on other digital toolsets.
Thanks for posting!
