1. Something useful that can be turned to commercial or other advantage: "Left-handed, power-hitting third basemen are a rare commodity in the big leagues" (Steve Guiremand).
2. A product or service that is indistinguishable from ones manufactured or provided by competing companies and that therefore sells primarily on the basis of price rather than quality or style.
3. Archaic Advantage; benefit.
