Amazon CEO Andy Jassy said on an earnings call on February 2 local time that the company has suspended the expansion of Amazon Fresh and unmanned convenience stores. Before it can embark on a massive expansion, he said, Amazon needs a unique form of store and keep its finances in good shape. “Retail is a tough industry.” Jassy said, “The process of expanding Amazon’s fresh service is flushing money down the toilet. But he added that the future of grocery supermarkets is omnichannel where online and offline coexist.
