This document discusses motivation and the self-concept in consumer behavior. It summarizes research on motivations for using online shopping carts. The research proposes that the frequency of shopping cart use depends on the intent to make a current purchase, seeking price promotions, perceived entertainment value, intent to organize items, and information-seeking behaviors. Hypotheses are presented relating these motivations to increased shopping cart use and likelihood of online buying. The results and implications suggest retailers should maintain promotions to stimulate cart use and buying, make purchasing convenient, and provide persistent carts that don't empty between sessions.
