Sales promotion encompasses activities, materials, devices, and techniques used to supplement advertising and marketing efforts, coordinating them with personal selling activities to boost product or service sales.
Sweepstakes are a popular type of sales promotion where lavish prizes are offered to entrants who have only to submit entries with their name and address by return mail or at a location determined by the sweepstakes sponsor, usually in a retail outlet where the sponsor's products are sold.
