Sales promotion consists of short-term marketing tactics used to encourage purchase. The goals are to drive immediate purchases, influence consumer behavior, and secure advertising effectiveness. Common techniques include coupons, samples, contests, premiums, and sponsorship events. Sales promotion targets different buyer types like loyal customers, competitors' customers, brand switchers, and price-sensitive buyers. While sales promotion can increase sales and achieve specific objectives in the short-term, overuse may cause customers to expect promotions regularly and wait to purchase until discounts are offered. This can negatively impact regular sales and brand perception over the long run.
