Amazon plans to grab a bigger share of the $1-trillion U.S. grocery business

Amazon on Wednesday announced a major expansion of its grocery delivery business, making thousands of perishable grocery items available via its Same-Day Delivery service and planning to expand from 1,000 cities to more than 2,300 by the end of 2025. The service will be free to Prime members on orders over $25, while shoppers without Prime membership will pay a fee. It’s telling that the announcement’s immediate impact on share prices of major grocery chains and competing delivery services was greater than the effect on Amazon stock.
