MapGasPrices.com allows consumers to map gas stations in their area, compare prices and find cheap gas. The site collects gas price data from numerous sources, including Oil Price and Information Services, OPIS. By finding the cheapest gas prices around and patronizing those stations, consumers can send a firm message to gas station owners and oil executives around the nation: ‘We are watching, so don’t gouge U.S. consumers.’ [PRWEB Oct 3, 2005]
