This proposal examines the impact of sales promotion on consumer buying behavior. Previous studies have found that promotional tools can positively influence consumer purchasing. The researcher aims to study how various sales promotion tools, such as buy-one-get-one-free offers and coupons, impact consumer buying behavior. A questionnaire will be distributed to collect data from respondents of different ages and genders on how promotional sales influence their purchasing opinions. The findings could help businesses better understand how to increase sales through the strategic use of sales promotion.
