Online retailers have raised the bar for convenience and fast delivery - and brick-and-mortar retailers are scrambling to keep up. To speed order fulfillment, they are shipping from stores that are closest to customers. To build on their strengths, they are focusing on the in-store customer experience. And to bring more online shoppers into stores, they are providing Buy Online, Pick Up In-Store (BOPUS) options. At the same time, they are rapidly investing in additional inventory and store labor to stay competitive.
