The COVID-19 pandemic has brought about unprecedented disruptions in global economies, significantly influencing consumer behaviour across different sectors. Lockdowns, health concerns, and uncertainty altered the way consumers perceive, purchase, and prioritize products and services. This research paper investigates the multidimensional changes in consumer behaviour in the post-COVID-19 era, particularly in the Indian context. The study reveals that digital transformation played a pivotal role in reshaping shopping habits, with a significant shift towards e-commerce and contactless transactions. Consumers demonstrated increased preference for health, hygiene, and wellness products, while discretionary and luxury spending saw a decline. Furthermore, financial insecurities led to more value-driven and conscious consumption. The research is based on primary data collected through a structured questionnaire from 200 respondents, analyzed using descriptive statistics and chi-square tests. The findings offer valuable insights for marketers, retailers, and policymakers to understand the emerging behavioural trends and adapt their strategies accordingly in a post-pandemic world.
