Windows Vista Business and Microsoft Office Small Business 2007 will be available at select CompuUSA stores as part of Microsoft Open Value or Microsoft Open Business licensing options—five copies or more at a 10 percent discount or more—part of an effort to make volume buying more obtainable for SMB (small and midsize business) and Home Office customers, more than 50 percent of whom turn to retail outlets for software, said Cynthia Bates, Microsoft's general manager of the small-business division for the U.S. Small and Mid-market Solutions & Partners Group.
