Bait-and-switch Bait-and-switch Bait-and-switch is a form of fraud used in retail sales but also employed in other contexts. First, customers are "baited" by merchants' advertising products or services at a low price, but when customers visit the store, they discover that the advertised goods are not available, or the customers are pressured by sales people to consider similar, but higher priced items ("switching"). Bait-and-switch techniques have a long and widespread history as a part of commercial culture. Many variations on the bait-and-switch appear, for example, in China's earliest book of stories about fraud, Zhang Yingyu's "The Book of Swindles" (c. 1617).
