What is a tactic in advertising used to deceive or trick a consumer in to buying a product or service?

One common tactic in advertising that can deceive consumers is the use of "bait and switch." This strategy involves promoting a product at a low price to attract customers, only to then inform them that the item is unavailable or of inferior quality, encouraging them to purchase a more expensive alternative. Other deceptive practices may include misleading claims, exaggerated benefits, or using fine print to obscure important information, all aimed at influencing consumer decisions.
