There are also many restrictions on price competition that are the direct result of government action. These include government-guaranteed parity prices in agriculture, trucking freight rates and airline fares before deregulation, ocean shipping rates, and many others. They also forbid selling more cheaply to one buyer or in one market than to others, or selling at ‘unreasonably low prices’ with the intent of destroying competition or eliminating a competitor. The act sought to protect small retailers (primarily independent grocery stores and drugstores ) from price and brokerage concession fees on bulk purchases from suppliers. Judging from the continuous decline in the number of small independent grocers, drugstores, and other retail businesses, and the expansion in the number and size of supermarket, the act was not very successful.
