promotion sales

A marketing technique which contributes to increase sales by creating a public interest in a product or service (coupons, discounts, special offers etc.). Usually its implementation is planned at a specific time but it can be introduced as contingencies. Promotion sales must satisfy the needs of the consumer without inducing disappointment or indifference to the brand.
