The extra notes would be kind of cool, but if it's existing stories, that's fine. I'm not much of a "collector" type so it'll be better (and cheaper) for me to just stick with buying the books in the selection I like. But for people who are collectors, this is an option.

Just make that Inquisitor tankard available separately. (Okay, I suppose when it comes to drinkware - particular for drinking beer or coffee/tea, I am a bit of a "collector," but I've also used every glass, mug, tankard, etc. I have.)
