Bait-and-switch is a deceptive advertising tactic that involves luring customers with an appealing offer, only to switch to a less attractive or more expensive option later. There are several synonyms for this unethical practice, including "deceptive advertising," "bait advertising," "false advertising," "bait pricing," "low-ball pricing," and "bait marketing." Other similar terms include "switch sell," "yo-yo sales," "confuse-and-lose," and "bait-or-switch." These terms are all used to describe tactics that mislead customers into purchasing products or services that are different from what they were promised or expected to receive. To avoid falling victim to these tactics, consumers should always read the fine print and be wary of offers that seem too good to be true.
