Amazon called the move 'one of the most significant grocery expansions' for the online retailer as it introduces thousands of perishable items into its existing network.

Amazon launched its same-day grocery delivery program in at least 1,000 cities and towns and has plans to expand to over 2,300 areas by end of 2025.

Walmart Plus, Instacart, and your local grocery store have more competition now that Amazon is delivering perishable groceries in more places, with free delivery for Prime subscribers on orders of $25 or more.
