The document discusses scaling online grocery shopping through click-and-collect options. It notes that while online grocery currently has a small market share, it is projected to grow significantly. Retailers need an omnichannel strategy to meet rising customer demand for online grocery and convenience options. Fulfilling grocery orders from existing stores presents challenges like picking accuracy and store crowding. Dedicated fulfillment centers address these issues while allowing multiple delivery options like home delivery, remote pickup, and store pickup. Fulfillment centers can improve efficiency and customer satisfaction through better stock control and order accuracy. Remote pickup points also provide more scalable capacity for retailers to meet customer demand for online grocery.
