This study uses a between-subjects experimental design to test the effect of two sales promotion formats (coupon versus markdown) with either high and low face values on consumer attitudes toward the deal, perceived product quality, and purchase intentions. The reputation of the retailer offering the deal is predicted to moderate the relationship between the promotional offer and consumer responses. Consumers perceive product quality to be higher when offered a high value coupon vs. markdown but there is no significant difference in perceived quality across promotion types when the promotion face value is low. When a deep price discount is offered by a retailer with a negative reputation, however, consumers have more favorable attitudes toward the deal and higher purchase intentions when provided with a markdown vs. coupon. Conversely, a high value coupon elicits more favorable evaluations than a markdown when the retailer has a positive reputation. When the value of the promotion is low and the retailer has a positive reputation, consumers have more positive deal attitudes and purchase intentions when offered a markdown vs. coupon. There is no significant difference in the effects of promotion type when the retailer has a negative reputation. The findings therefore establish retailer reputation as an important moderator of sales promotions effectiveness. This research is limited by the use of a single product category and a student sample. Process measures are also needed to validate the proposed theoretical conceptualization. The results provide managers insight into the type and value of the sales promotion to offer based on consumer perceptions of the retailer's reputation in the market.
