Step-by-step explanation:
The marketing method that the sandwich shop is using is called targeted marketing. Targeted marketing involves identifying a specific group of consumers based on certain demographics or characteristics to tailor marketing efforts towards them. In this case, the sandwich shop is using the age and income demographics provided by the United States Postal Service to determine who will receive the coupon.
