Abstract Although price discounts are by far the most common form of sales promotions employed by firms, the increasing use of premiums as a promotional strategy may imply that they are occupying a more important place in the promotional strategy. Since price discounts are quite costly and can reduce consumers' reference prices, undermine perception of quality, and hurt brand equity, it is crucial to know what type of promotion is the most preferred and valued by consumers. As the most recent works in the field have argued that the promotional benefit level is an important determinant of promotional effectiveness, this research reports the results of two experimental studies that investigated the interaction effect between promotional benefit level and promotion type across three levels of benefit (low, moderate, high). The results obtained suggest that at high benefit levels price discounts are more effective than premiums, while the opposite occurs at low levels. However, a similar evaluation of promotional tools was found at moderate benefit levels. The findings offer guidance to managers who might benefit from knowing what is the best strategy to promote their products and services. Our work also extends prior related research because, to this date, the effectiveness of price discounts and premiums across promotional benefit levels is an under‐researched issue. © 2009 Wiley Periodicals, Inc.
