Sales promotion strategy is very useful to meet the needs of your business short-term goals. You can do to spend on old stock, reduce existing stock in the warehouse or to meet existing stock at the retailer level before your competitors introduce their products.

Sales promotion strategies can also make "marginal buyers" come buy your product. Marginal buyers are those who buy only when a product or service is in "promotion". This marginal buyer bias is not favored by the company.
