Commodities

Note the prefix - commo - as in "common." 

Commodities are goods or services that are more or less the same wherever you buy them, and in whatever form you receive them.

Coconuts, gasoline, water, and sugar are all strictly commodities. Ferrari race cars, rare Italian espresso machines, a Mona Lisa painting, and an intelligent, mature congressman are all non-commodities, which are rightly prized. Or at least should be.
