How many people are walking through B&N, phones in hand, shopping the book shelves and ordering through Amazon?
I wouldn’t be at all surprised if the toys etc. subsidize the books, i.e., for occasions when you need something right now.
People get the bookstores they deserve. A town near me has a wonderful bookstore of the old type, esoteric titles, staff recommendations, etc. And I know it’s because the people there don’t go home and order online.
