Abstract
The location of a container and the location of a storage device that stores a particular item are determined. A determination is made that the particular item is placed in the container. The locations of the particular item and the container are tracked as the container moves through a premises. For a purchase-related transaction, a determination is made whether the location of the particular item corresponds to the location of the container. If the location of the particular item corresponds to the location of the container, a cost for the particular item is included in the purchase-related transaction. If not, the cost for the particular item is not included in the purchase-related transaction, and the location of the particular item is accounted for.
