What is the best example of bait and switch advertising?

The situation described in the example aligns closely with the definition of bait and switch advertising, which involves promoting a product or service at an attractive price to lure customers in, only to attempt to sell them a different, usually more expensive item once they arrive.

In this instance, the camera store advertises a low price for a specific model, attracting potential buyers. However, when customers come in to purchase the advertised item, they find that it is sold out and are instead offered only a more expensive model. This practice is deceptive because it fails to provide the advertised product at the advertised price, which misleads consumers and undermines their ability to make informed purchasing decisions.

This method is considered unethical and is often prohibited by consumer protection laws because it exploits customers’ trust and can lead to dissatisfaction. The other scenarios, while potentially misleading in certain contexts, do not clearly fit the bait and switch definition in the same way. For example, limited stock availability can be a legitimate business practice as long as it's disclosed, and promotional offers such as "buy-one-get-one-free" don't inherently mislead customers about pricing.
