A system for use by a bricks-and-mortar retailer has RF tags on items of merchandise ("item tags") and has large antennas in large areas of a retail space. Intermediate tags are communicatively coupled to the large antennas and also to the item tags. The locations of the intermediate tags are known, and thus the location of an item is known because it is communicatively coupled with one of the intermediate tags. A customer visits a web site and orders an item for later pickup at the store. Store personnel then go to the location of the item, pick the item, and put it at a store location for later pickup. The customer can travel to the store and present an identifying card and pick up the item.
