Plummeting gas prices have been good news for drivers.
A quick squeeze at the pump, and it's easy to see the numbers don't climb as fast as they have in the past. Gas prices have fallen $0.46 per gallon in the last two months.
The Lundberg Survey of gas prices attributes the drop to refinery problems that were being fixed just as seasonal demand started shrinking. Crude oil is also cheaper, following a period of steadily rising prices.
Gas prices could keep falling, too, according to the survey's publisher. The national average for gasoline is now $3.38 per gallon. The most expensive gas averages $3.85 in Long Island, New York.
The cheapest averages $3.04 in Memphis, Tennessee.
