Bait pricing lures customers with an extremely low-priced product, expecting them to also buy regular-priced items once in the store.
An electronics store advertises a TV at an unbelievably low price. Customers arrive and either buy that TV plus accessories, or salespeople upsell them to better (and more expensive) models.
Also known as 'bait and switch,' this practice may be legally restricted in some jurisdictions if the advertised product is intentionally understocked or unavailable. Ethical application means genuinely offering the advertised deal while presenting better alternatives.
