Globally, online retail sales during 2017 were observed to be $2.38 trillion, and it has been estimated to hit $6.54 trillion by 2023 (eMarketer, 2019). Specifically, the Indian online retail sales have been estimated to be $120 billion in terms of the gross merchandise value (GMV) by the end of 2025 (IBEF, 2021). Further, it has also been estimated that the total number of online shoppers will increase to 175 million, and about 33% of the customers will drive two-thirds of their total shopping via the Internet (Google-A.T. Kearney, 2016). This prolific growth in the online retail industry in India is attributed to some key factors such as high-level smartphone usage, high-speed Internet, IT innovations, increasing purchasing power and an incredible increase in Internet penetration (Raman, 2019). The young population of India is going to propel the Indian e-commerce market to exceed the e-commerce market of the USA. As a result, India will take the second-largest position in the global e- commerce industry by 2034. Despite tremendous growth of online purchasing, voluminous consumers signify their dissatisfaction with online shopping experiences (Luo et al., 2012; SAJBS 12,1 54 The current issue and full text archive of this journal is available on Emerald Insight at: https://www.emerald.com/insight/2398-628X.htm Received 3 July 2020 Revised 29 November 2020 10 February 2021 14 March 2021 7 April 2021 Accepted 11 April 2021 South Asian Journal of Business Studies Vol. 12 No. 1, 2023 pp. 54-78 © Emerald Publishing Limited 2398-628X DOI 10.1108/SAJBS-07-2020-0223
