The primary objective of this research is to identify the impact of E-Commerce usage on students’ consumptive behavior. Using a quantitative method, data was collected through the distribution of questionnaires. The analysis of the questionnaires, employing a validity test, confirmed that all data obtained were valid and suitable for further investigation. The findings reveal that consumptive behavior significantly impacts human life, including financial, academic, and social aspects.
