The Wegmans grocery store chain operates 90 stores across six states in the Northeast U. S. And continues to grow. Like many grocery stores, it is trying to respond to changes in the external environment and now offers Instacart, a service allowing customers to shop online and receive delivery within an hour depending on their location. Wegmans believes the added convenience and time-saving aspects of grocery delivery will lead to greater customer satisfaction, increased revenues, and profitability.
