Final answer:
Major retailers use loyalty programs to attract customers. Economists call a "good deal" a consumer surplus. Loyalty programs can lead to increased consumer satisfaction and purchase frequency.
Step-by-step explanation:
Walmart, Target, Macy's, and other major retailers offer handy loyalty programs that pull customers to both their websites and stores.
An economist might refer to a situation where a shopper gets a "good deal" as the consumer achieving consumer surplus, which is the difference between what consumers are willing to pay for a good or service and what they actually pay.
By taking advantage of loyalty programs, discounts, or promotions, consumers often feel that they're receiving greater value for their money, resulting in a positive shopping experience and potentially more frequent purchases.
