This rapid review synthesizes recent and foundational research (2020–2025) examining how shipping fees, perceived price dispersion, delivery touchpoints, and “psychological pain” influence consumer behavior and operational decision-making. Evidence from marketing, logistics, and optimization studies shows that consumers are highly sensitive to delivery costs and pricing fairness, with shipping-related frictions negatively impacting satisfaction and purchase decisions. Studies also highlight downstream operational impacts such as increased product returns due to free shipping promotions and improved marketplace performance through delivery consolidation. Additionally, research from emergency logistics introduces psychological pain as a measurable cost factor in allocation and transport models. The review concludes with managerial implications for e-commerce firms and policy implications for logistics planning, and proposes future research directions emphasizing behavioral realism and contextual generalizability.
