Step-by-step explanation:
Direct mail flyers, in-store samples, and coupons are all examples of below the line promotion. Below the line promotion refers to promotional activities that are targeted directly at the customers, rather than using mass media channels.
These promotional activities are aimed at creating a direct interaction between the brand and the customer, such as distributing flyers, providing samples, or offering coupons to generate immediate sales or increase customer awareness.
