Bait and Switch is "A dishonest sales practice in which a business advertises a bargain price for an item in order to draw customers in and then tells the prospective buyer that the advertised item is of poor quality or no longer available and attempts to switch the customer to a more expensive product. In most states this practice is a crime and can also be the basis for a personal lawsuit if damages can be proved." Cornell Legal Information Institute.
Researching this topic may require looking at state and federal law.
