Amazon.com Inc proved it can use bargain buzz to sell a lot of gadgets on a random day in July. This year, it’s hoping excitement around Prime Day gets shoppers to change how they buy groceries. 

Amazon’s fourth annual Prime Day – 36 hours of sales beginning July 16 – will be its first since closing the US$13.7bil (RM55.06bil) purchase of Whole Foods Market Inc. It is offering discounted strawberries, chicken breasts and cod fillets to lure people into its brick-and-mortar stores, as well as enticements to get them to try grocery delivery for the first time.
