Inside Amazon’s Battle to Break Into the $800 Billion Grocery Market

After almost a decade of food retail experiments with little success online, the e-commerce giant is embracing the physical stores it once shunned.

“Very wasteful” isn’t a phrase usually associated with Amazon.com Inc., which is so cost-conscious it once removed the light bulbs from its cafeteria’s vending machines. But after spending several months analyzing the online retailer’s grocery-shipping hubs back in 2014, that’s exactly how a mechanical engineering student described its approach to selling bananas.

Workers at Amazon Fresh, the company’s grocery-delivery business, threw away about a third of the bananas it purchased because the service only sold the fruit in bunches of five, the student concluded. Employees trimmed each bunch down to size and chucked the excess.
