Why would you buy a book you don't intend to read? Is it kind of like buying home decorations? I mean I know how my habits work, I go to a bookstore, browse books, start reading wait to see if the story catches or doesn't, buy it or keep looking. Once I've got the hook on that story I can't shelve it without finishing it. I don't understand how you could not. Maybe people buy the books with a different intention?
