E-commerce major Amazon which had announced an investment of two billion US dollar to expand its operations in India last year, continues to invest “very heavily” in the Indian market.

CEO Brian T. Olsavsky said the company has seen sales quadruple during the festive season compared to last year. He, however, declined to disclose investment details.

Olsavsky said that the company has been adding 40,000 products a day so far this year on its platform and the number of sellers has grown more than 250 per cent year-on-year with about 90 per cent of those sellers using Amazon’s logistics and warehouse services.

India is one of the fastest growing markets for Amazon. The company is investing heavily into setting up warehouses across the country to speed up delivery and efficiency.
