Avenue Supermarts, which runs the DMart retail chain, saw its online sales more than double during FY19 to Rs 144 crore despite operating only in Mumbai. The country's most valuable retailer by market capitalisation, however, posted a net loss of Rs 51 crore in the two-year old e-commerce venture. "We entered this business on a pilot basis since we thought we can learn from it and also be part of the channel ecosystem. We can't comment on its growth strategy as its still an experiment for us," said Neville Noronha, CEO of Avenue Supermarts.
