The proliferation of e-commerce platforms has profoundly reshaped consumer purchasing behavior, offering unprecedented convenience, product diversity, reliability assurances, competitive pricing, and compelling promotional incentives.

This research employed a quantitative approach, with data gathered via questionnaires administered to respondents who made purchases on the Shopee e-commerce platform in Pekanbaru. The collected data were analyzed using multiple linear regression to examine the influence of price perception, promotion, and purchasing decisions. The research findings indicate that price perception significantly influences purchasing decisions on Shopee e-commerce in Pekanbaru. This finding stands in stark contrast to promotions, which showed no significant influence on purchasing decisions.
