This paper aims to examine the relationship between product, price, place, promotion, trust, and intention to purchase. The sample of this study was 125 undergraduate students at a university located in Suphanburi, Thailand. Due to the Covid-19 pandemic, an online questionnaire was administered to collect data from targeted samples. The gathered data was analyzed using ordinary multiple regression analysis to test the relationship between independent and dependent variables. The findings reveal that trust is the most crucial factor affecting purchase intention. However, product, price, place, and promotion do not influence the intention to purchase products and services from the Lazada application. Hence, building customer trust would be beneficial for Lazada to compete with other online shopping applications.
