In its continuing quest to promote trade show consolidation, the Plumbing Manufacturers Institute is promoting its “Revenue Enhancement Formula,” a plan to develop a single, extended, annual building show format, even if it results in significant increases in booth space charges. In PMI's formula, the consolidation of three existing shows could absorb a 40 percent increase in booth fees. For more information, contact PMI Executive Director Barb Higgens at 847/884-9764.
