Note: Bookstores can’t stock all 12 million books that are out there in the world. Most bookstores stock less than 20,000 titles. They stock the books that sell. They stock the books that their customers ask for.
If you want to sell books through bookstores, you’ve got to get your tribe, the people who follow you, the people who have been waiting for your book to be finished — you’ve got to get those people to ask their local bookstores to stock your book.
