Aggregate award means an arrangement whereby two or more separately-priced line items are combined for award to that bidder whose bid will result in the lowest overall cost to the Government for the line items as a group. The individual price for each item does not have to be the lowest bid received. (See also the definition of a “line item” in FAR 3.302.)
