The U.S. average price of gasoline ($3.03/gal) continues its slide to levels last seen in December of 2010… and today, more than one-half of the nation’s gas stations offer regular gasoline at prices below $3 per gallon. GasBuddy reports that of more than 133,000 gas stations from which it gathers retail price data via crowd-sourcing, the ‘tipping point’ in this year’s autumn price decline was reached over the weekend when the number of stations selling gas below $3 climbed to 50% of all retailers across the U.S. The last time 50% of the nation’s fuel retailers were priced below $3 was Dec. 28, 2010.
