Amazon plans to introduce same-day delivery as a new service option, aiming to address customer concerns about buying perishable food online and to compete with rivals like Walmart. The initiative entails optimizing logistics, expanding its network of warehouses, and utilizing advanced technology to enhance delivery efficiency, thereby generating new revenue streams through Prime membership. Despite facing challenges with last-mile delivery and reliance on third-party logistics, Amazon is focused on transforming its delivery model to adapt to customer demands and environmental goals.
