Sales promotion refers to the discount, contests, special offers, gifts, etc. The purpose is to increase casino sales. The sales promotion is not directed at the customer but at the intermediaries who provide the casinos information to the customer. The casino might provide them with a familiarization trip and in return they promote the casinos product (Denis P. Rudd, 1996). The travel agents may sell more of the casino trips through attractive display posters. Most likely casino may offer their new product by discount, specials. In this way, sales promotion can increase the economic income effectively.
