Hi Blit_Wizbok! At this point in time, only Paizo has a cross-platform discount program. WotC offers no similar coordination. Even their own (now) company DnDBeyond offers no discount to owners of physical books. In large pat, this is due to the fact that they are essentially different products, with a tremendous amount of work going into preparing them for their entirely different uses. A common comparison is that owning a physical copy of the Lord of the Rings grants no discount on movie tickets to the film adaptation.
