The technique of "bait and switch" is not a promotional tactic used by sellers. Instead, it is considered a form of fraud. With this technique, customers are attracted ("baited") by attractive prices on certain goods. However, when they visit the store, the items are unavailable or more expensive, at which point sellers try to pressure buyers to buy something else ("switch").
