In the 1990s, Pepsi ran a commercial: Buy soda, get points, redeem points for cool stuff. T-shirts, sunglasses... and for 7 million points, a Harrier Jump Jet. It was obviously a joke. Or was it? John Leonard, a 21-year-old business student, did the math. He realized he could buy the points for $700,000—a steal for a $23 million military aircraft. He raised the money. He sent the check. Pepsi panicked. The ensuing legal battle, Leonard v. Pepsico, became a landmark case in contract law. This book is a hilarious and insightful look at the "Cola Wars," the psychology of audacious marketing, and the moment a corporation realized that if you promise the world to a clever student, he might actually try to collect it.
