"Last week saw an impressive decline in crude oil and gasoline futures, and accordingly, motorists in most areas of the U.S. have seen retail gasoline prices decline. In some areas, price have outright plunged to under $3 a gallon," said Patrick DeHaan, GasBuddy.com Senior Petroleum Analyst.
"While social networking sites are abuzz about the decline, be warned that the market does remain extremely sensitive to geopolitical issues and refinery maintenance season is right around the corner," DeHaan adds.
