Answer:
The answer is bait and switch pricing.
Step-by-step explanation:
Bait and switch pricing is a form of deceptive pricing that describes the practice whereby customers are lured into a store by offers or claims about the existence of a quality or low priced item which turns out to be unavailable.
The retail store then tries to sell or persuade the customer to buy a similar item at a higher price. This kind of pricing is widely considered as a fraudulent form of retail sales and most countries have laws against it.
