In Palm Beach County, a 7-Eleven located at 4774 S Military Trail and Melaleuca Lane in suburban Lake Worth, Fla., was selling regular gas for $2.02.
Industry analyst Trilby Lundberg said Sunday that the pump price fell even though crude oil prices gained strength, as gasoline supply outweighed demand.
Further price drops are likely if crude oil prices don't skyrocket, because the Sept. 15 change to winter grade gasoline comes with a cost cut in much of the country.
The cheapest price recorded in the continental United States was Charleston, South Carolina, at $1.94.
The highest was $3.31 a gallon in Los Angeles.
