Covid-19's influence on the retail industry is leading to increased internet purchasing. This research is all about studying the causes and effects of this shift. The COVID-19 crisis, customer behavior literature and COVID-19 research are used to explain how online purchasing habits have evolved. The study aimed to identify the changes in consumers' internet purchase habits. We conducted descriptive single-case research to examine internet customer behavior. Consumers who completed online purchases within the time frame of the research were used as the study's unit of analysis. Results suggest that online users respond, cope, and ultimately adapt when confronted with stressful circumstances, proving the effectiveness of the react-cope-adapt paradigm for limited consumer behavior. Academics and merchants alike may utilize our results in the case of future crises to enhance their product selection, advertising, and distribution to better understand customer behavior in these times
