(Robinson) – The Robinson Wal-Mart has joined stores across the nation and officially launched its “Online Grocery Pick-Up” service. The store held a ribbon-cutting this morning and the service is now live. “OGP” is the latest effort by Wal-Mart to better serve its customers with limited mobility or limited time. Customers can now order their grocery items through the Wal-Mart app and schedule a pick-up time and items will be ready and waiting for you when you arrive at the store. There is a $30 minimum per order.
