Through a website, people can order groceries and they will be ready and bagged when they arrive at the store. This prevents one of the most expensive aspects of running a grocery store; shrink. Customers never enter the store to break or steal merchandise or leave out cold items in the bread aisle. This also eliminates the need for a person on staff to do "returns" and allows for customers to save time, usually over an hour, by not walking the aisles of the grocery store. All in combination, this leads to lower prices and time spent more efficiently.
