At Powell’s Books, if a customer tries to buy a used book that’s out of stock, they’ll send them a new one for the same price. That way, instead of waiting for the book to come back in stock, the customer gets upgraded.

This is how a small bookseller competes with someone like Amazon. When something goes wrong, they don’t just fix the problem, they give them a reason to come back.
