I hope I didn't take this quote out of context, but what brick and mortar stores do you visit??? At least in Michigan, the ones that do the best are the ones that carry the biggest selection of back issues and wall books, among other things (toys, cards, Manga, etc.). The stores that have tried surviving with only Manga, Pops, and new release comics...die a slow death.
Again, what comic stores do you go to that don't have comics??? I would not consider those "comic" stores.
Edit - Sorry. Read it wrong. Bookstores. Not comic stores.
