This research evaluates the impact of sales promotional tools, namely coupon, price discount, free sample, bonus pack, and in-store display, on product trial and repurchase behaviour of consumers. In addition, the moderation role of fear of losing face (or embarrassment) on the relationship between the sales promotional tools and product trial was examined. The sample points for the research were supermarkets in Kota Kinabalu, Malaysia. A total of 420 randomly selected customers were surveyed using structured questionnaire, out of which, 312 usable responses were received. The results of data analysis show that price discounts, free samples, bonus packs, and in-store display are associated with product trial. Coupon does not have any significant effect on product trial. Trial determines repurchase behaviour and also mediates in the relationship between sales promotions and repurchase. Fear of losing face significantly moderates the relationship between in-store display and product trial. Details of the findings and their implications are discussed.
