A network connected delivery box includes an input unit for inputting a user code. A communication unit communicates with a computer through the network so that an electrically controlled lock in the delivery box can be opened by a signal from the computer when the input user code matches a valid user code stored in the computer. Also provided is a method of managing purchase and delivery information associated with deliveries to a delivery box by storing, at a central computer, delivery information for each delivery by a delivery company. Aggregate and average delivery information is calculated and presented to a delivery box user to make an informed selection of a delivery company.
