e/Grocery trading

Information
has gloss	eng: Grocery trading is an industry, historically not well known by the general public, in which grocery "traders" or grocery trading companies buy and sell (trade) blue chip grocery store items such as Cheerios and Alpo amongst the nation's largest supermarket chains based on price discrepancies from chain to chain. The manufacturers who produce grocery products are deliberately ambiguous in their selling practices and pricing of their goods using artificial "list prices" and artificial "special savings" in an effort to fool their customers (buyers at large supermarket chains) and maximize their profits.
