A small bakery cannot engage in price manipulation for a meaningful time or volume to oust competition, that activity is completely different category.
Anyways the fundamental problem with most bookstores that aren't Barnes and Noble is that they all do a terrible job of having the things I want to read. When the local artisan bookstore won't bother to stock RA Salvatore or even fucking Tolkien because it's too "low brow" I don't have a whole lot of empathy for them. I actually do enjoy bookstores when they aren't merely a far more inconvenient way to order books from a large corporate distribution center.
