Some players and GM's already have one or two copies of a book you offer. Like Volo's or Mordenkainen's and we don't really find reading the lore in it on Roll20 very acceptable, but we would love to use your official tokens. An option to buy only the tokens and NPC page of a monster (his stats and moves not including his lore) would be an amazing way to make game masters like me not even hesitate about buying a book we already own again. Instead of making our own 260 tokens from the book rules we can use your tokens but not buy into the full book and an adjusted price.
