“As if to prove his singular obsession with customer experience, Bezos placed an expensive bet, hitching Amazon’s Quidditch broom to the rising fantasy series Harry Potter. In July, author J. K. Rowling published the fourth book in the series, Harry Potter and the Goblet of Fire. Amazon offered a 40 percent discount on the book and express delivery so customers would get it on Saturday, July 8—the day the book was released—for the cost of regular delivery. Amazon lost a few dollars on each of about 255,000 orders, just the kind of money-losing gambit that frustrated Wall Street. But Bezos refused to see it as anything other than a move to build customer loyalty. “That either-or mentality, that if you are doing something good for customers it must be bad for shareholders, is very amateurish,” he said in our interview that summer. The Harry Potter promotion unsettled even the executives working on it. “I was thinking, Holy shit, this is a lot of money,” says Lyn Blake, the Amazon executive in charge of books at the time. She was later inclined to admit that Bezos was right. “We were able to assess all the good press and heard all these stories from people who were meeting their deliverymen at their front doors. And we got these testimonials back from drivers. It was the best day of their lives.” Amazon was mentioned in some seven hundred stories about the new Harry Potter novel in June and July that year.”
