CAMARILLO, Calif. (AP) -- An analyst says the average price of regular-grade gasoline fell half a cent nationally over the past two weeks to $2.40 a gallon.
However, industry analyst Trilby Lundberg of the Lundberg Survey said Sunday that gas prices actually rose in several Western and Midwestern cities.
A sharp decline in the rest of the country kept prices down overall.
Lundberg says the average price is 9 cents higher than it was a year ago.
The highest average gas price, $3.10 a gallon, was in the San Francisco Bay Area. The lowest, $2.02 a gallon, was in Jackson, Mississippi.
Lundberg says crude oil prices rose during the previous two weeks, but retailers have been slow to pass those increases on to consumers.
