This study explores changing consumer behaviours regarding online shopping in South India (Telangana, Andhra Pradesh, Tamil Nadu, and Karnataka) during the period 2020–2025. Using data from 100 surveyed participants evenly split across the four states, the research analyses shopping frequency, drivers, payment trends, satisfaction, and challenges, employing statistical tools such as percentage analysis, regression, and ANOVA. The findings indicate that factors like digital literacy, convenience, and an expanded variety of online offerings fuel high adoption, while issues of trust and delivery logistics remain persistent concerns. The study concludes with recommendations tailored for the region's e-commerce stakeholders.
