Originality/Value;Furthermore, the samples were 100 consumers of the Shopee Marketplace located in Lampung Province, Indonesia. The data were obtained through a questionnaire and analyzed using descriptive statistics and Partial Least Squares (PLS) analysis. Findings; The results showed online promotions and website quality had a significant influence on online impulsive purchases, while trust had no significant influence. Also, online impulsive purchases were found to have a significant influence on positive emotions, but no significant influence on negative emotions.
