The most suitable form of marketing communication for this case is sales promotion.
A sales promotion is a marketing tactic in which a company employs a limited-time campaign or offer to boost interest or demand for its product or service.
A company may decide to utilize a sales promotion (or "promo") for a variety of reasons, but the main one is to increase sales. Sales increases could be required to meet a quota as a deadline draws near or to spread the word of a new product.

This increases sales among all demographics without depleting the company's inventory or revenue levels.
