Sales promotion is used by various organizations to encourage buying response among their customers. Although it is an effective tool in marketing, few studies have been conducted on sales promotion on buying response using customer emotions as a mediating factor.

The model was validated by conducting a survey with a convenience sampling technique on 664 customers. The data collected were processed using a structural equation modeling approach. The result shows that a bonus pack, coupons, sample, price discount, and rebate have a relation with customer buying response.

The study suggested that managers must create new value for their product to build an emotional connection with the product
