Definition of impulsive purchase
Impulsive purchase is first defined as an “unplanned” purchase by DuPont studies, the difference between a consumer’s total purchase and those were listed as intended purchase before entering a store (Rook 1987). Stern (1962) and Willett (1969) criticized that the definition of unplanned impulsive purchase is too vague and encompasses too many different types of behavior. Stern (1962) categorized impulsive purchase into four different kinds of buying, as shown in table 1.
