The term price originated in c. 1200, pris "value, worth; praise," later "cost, recompense, prize" (mid-13c.), from Old French pris "price, value, wages, reward," also "honor, fame, praise, prize" (Modern French prix), from Late Latin precium, from Latin pretium "reward, prize, value, worth," from PIE *pret-yo-, suffixed form of *pret-, extended form of root *per- (5) "to traffic in, to sell." Price is arguably the most important of the decision drivers. Sales people are taught to save price for last when negotiating with customers. So what is the value or worth of your product? Is your product a prize for customers? Does the product give fame to the client?
