I'm not sure how difficult it would be to verify, but I already have paid for and own the 5e Monster Manual, Volos Guide To Monsters, and more books. I would love to be able to access these online features, but paying AGAIN for the same thing I own isn't really an ideal situation. So I'd like if at all possible (maybe through serial numbers), if we could have a feature that lets us access these compendium perks if we already own the physical copies.
