CAMARILLO, Calif. (AP) — The average price of gasoline has fallen 4 cents a gallon over the past two weeks and 20 cents since this time last year.

The Lundberg Survey of gas prices reports that nationwide a gallon of regular costs $3.56. Midgrade costs an average of $3.74 and premium is $3.88.

According to analyst Trilby Lundberg, the lower pump prices are largely a result of good domestic supplies reducing the impact of higher foreign oil prices.

Of the cities surveyed in the Lower 48 states, Charleston, S.C., has the nation's lowest average price for regular at $3.22. The Long Island, N.Y., region has the highest at $3.82.
