TicketMaster recently settled a pricing-related class action lawsuit that provides important pricing lessons to all businesses. In addition to paying for admission to an event, the ticketing giant used to tack on additional charges such as convenience, facility, order-processing, and delivery fees to purchases. The class action plaintiffs claimed these fees were misleading; had they known TicketMaster was making profit off the order-processing and delivery fees, the suit claimed, they might not have purchased.
