This paper advances research into impulse buying by examining how this behaviour is reinforced/curtailed, highlighting the primary role of the post-purchase experience in encouraging future impulse buying behaviour. Extant research emphasizes the role of the purchase experience, that is, psychological benefits attained from the impulse purchase experience itself, as a reinforcer of impulse buying. Conversely, this paper uses experiments to demonstrate that it is the post-purchase experience, not the purchase experience, that reinforces or curtails future impulse buying. Indeed, irrespective of the valence of the purchase experience, a negative post-purchase experience (whereby a product or service is found to have limited use/does not deliver expected benefits) results in post-purchase regret, which in turn curtails future impulse buying. In contrast, a positive post-purchase experience reinforces impulse buying. This research also demonstrates that consumers utilize three types of coping mechanisms to mitigate post-purchase regret, that is, planful problem solving, positive reinterpretation, or mental disengagement. However, although the use of planful problem solving curtails future impulse buying, use of the other two mechanisms results in behaviour reinforcement. These findings have several important implications for both marketers and consumers, which the authors discuss in detail.
