A third party that stores inventory can also increase the supply chain surplus 
by aggregating inbound and outbound transportation. Given the small size of 
retail outlets, a distributor aggregates delivery for several manufacturers, 
significantly lowering the outbound transportation cost. This form of 
aggregation is most effective if the intermediary stocks products from many 
suppliers and serves many customers, each ordering in small quantities. This 
form of aggregation becomes less effective as the scale of shipment from a 
supplier to customer grows. The supermarkets typically get full trucks 
delivered to their DCs or stores and do not need distributors for further 
aggregation.
