Growing at a rate of about 15 per cent and registering a double digit growth figure every year, the total retail sales in India is likely to rise from $717.73 bn during calendar year 2014 to $1,244.58 bn in 2018, says a study by the Associated Chambers of Commerce and Industry of India (ASSOCHAM) and financial advisory services provider Resurgent India. In 2017, about 100 mn consumers purchased online and the number is expected to cross 120 mn by 2020 with the rise of digital natives, better infrastructure in terms of logistics, broadband and Internet-ready devices to fuel the demand in e-commerce, an Assocham said citing the study.
