Understanding Planning for Unplanned Purchases: Antecedents and Exploitation of In-Store Slack Available to Purchase

In-store slack is the portion of the mental budget that is reserved for unplanned purchases. In this paper, the study of Stilley et al. (2010a,b) on the existence and exploitation of in-store slack is replicated and extended through the investigation of instore slack in varying store formats and with regard to different product categories, confirming the existence of in-store slack and demonstrating its context-dependent size and utilization.
