The effect of item reduction on assortment satisfaction—A consideration of the category of red wine in a controlled retail setting

This study aims to investigate the effect of item reduction on assortment satisfaction within the red wine category. The study conducted an online experiment using a simulated online wine store. Lowest selling wines were removed after the first buying phase, and the respondents repeated the browsing process in the reduced assortment. A questionnaire measured the shift in perceptions. The results show that assortment perceptions can be maintained in the face of item reduction. There is also a strong association between category familiarity and assortment satisfaction, with differing levels of assortment satisfaction between high and low category familiarity groups. The presence of a favourite item also plays a role in maintaining assortment perceptions. The results suggest that retail managers can reduce assortments by removing low selling items while not affecting customers' assortment perceptions. Furthermore item reduction can be used to increase consumers' satisfaction if they are unfamiliar with the product category. This particular study is limited in the sense that the results were obtained exclusively in an online environment. Future studies may therefore be useful in validating these results in brick and mortar wine outlets.

► A tipping point exists between product assortment levels and consumer satisfaction.
► Item reduction may be used to improve consumer satisfaction.
► Low selling items should only be removed if high selling items remain.
► Consumer familiarity with the category should be taken into consideration.
