Commodity

Note the prefix: commo, as in "common."

A commodity is a good or service that is more or less the same wherever you buy it, and in whatever form you receive it. Coconuts, gasoline, water, and sugar are all strictly commodities. Ferrari race cars, rare Italian espresso machines, the Mona Lisa, and an intelligent, mature congressman are all non-commodities, which are rightly prized. Or, at least...should be.
