Survey: Average US gasoline price drops 11 cents to $2.71 a gallon

The average price of gasoline has dropped 11 cents over the past two weeks to $2.71 a gallon.

Industry analyst Trilby Lundberg said Sunday that the current average sits 81 cents below the year-ago price.

The cheapest price recorded in the continental United States was $2.19 a gallon in Charleston, South Carolina.

The highest was $3.80 a gallon in Los Angeles. California saw a 21-cent price drop over the past two weeks — following a huge spike caused by a brief supply shortage. Lundberg says supplies are flowing again and pump prices are poised to drop further in the Golden State.

The national average price of diesel was down 8 cents over the same period to $2.78 a gallon.
