Which decision rule focuses on discounts and promotions for a product?

The decision rule that focuses on discounts and promotions for a product is the promotion rule. This concept pertains specifically to how consumers are influenced by promotional tactics such as discounts, sales, and special offers when making purchasing decisions. The promotion rule suggests that consumers often prioritize deals and incentives that make a product more appealing financially, leading them to alter their preferences or to choose products based on the perceived value provided by ongoing promotions.

In contrast, the other options focus on different aspects of consumer behavior. For instance, the affect referral rule emphasizes the impact of emotions and feelings on consumer decision-making, rather than objective pricing or promotional incentives. The concept of an important person relates to social influences, where recommendations or endorsements from significant individuals can affect choices, but does not address discounts. Lastly, the wait and see approach pertains to a more cautious consumer behavior, where individuals delay their purchasing decisions rather than actively seeking out promotions. Each of these alternatives highlights different motivational factors in consumer behavior, thus reinforcing the distinct focus of the promotion rule on promotional strategies.
