These networks vary in nature and structure, but share a common objective of improved competitiveness through more effective buying, pooled marketing and/or national brand recognition. At a minimum, these networks have enabled independent retailers to achieve a relative degree of competitive parity with multiples, through participation in strategic brand building.
