An online survey identified performance expectancy, effort expectancy, social influence, and an affective component as significant predictors of consumers’ intentions to use these systems for non-food products. The “refill at home” system was most favored, followed by “refill on the go” and “return on the go”. Hence, consumers prefer larger refill packaging but are also open to in-store refilling or returning.
