Abstract: This research examines how a traditional handwritten paper shopping list differs from a digital shopping list created on smart devices in influencing consumers’ planning and shopping behavior. We propose that a paper shopping list includes more items than a digital shopping list, and products on a paper shopping list are less hedonic than those on a digital shopping list. Furthermore, the use of a digital shopping list leads to more unplanned and hedonic purchases in the store, while the use of a paper shopping list results in more planned purchases. We also discuss psychological processes underlying these effects. We conduct three studies in which we manipulate shopping list type and track consumers’ actual purchases to provide support for our hypotheses.
