Price can be dated back to mankinds earliest forms of barter or trade, whenour ancient ancestors were counting small seashells used for exchanging goodsamongst one another, from these primitive origins price has passed down to to-days society.

And now in the modern era, we could never live without a tiny label that hasan items price on it. Everything has a price, and with large price fluctuations fromchanges in the market, a price problem has been produced.
