An Out of Home (OOH) Network is a convenient parcel pick up and drop off network for consumers, including parcel lockers and over-the-counter locations. Retailers can offer Click & Collect and Returns to their consumers, who are able to pick up and drop off their parcels at an Out of Home location and at a time that suits them. Pick up or drop off from an Out of Home location is also more sustainable than home delivery, as it reduces carrier trips, therefore congestion on roads and carbon emissions.
