RALEIGH - You may have noticed it's costing a little less to fill up your vehicle lately. Gas prices in the state have fallen 20 cents over the past month and 45 cents over the last year.

Triple-A Carolinas Angela Daley says there's one major factor for the lower prices at the pump.

"The biggest factor affecting gas prices right now is lower demand. the summer driving season is over, so we usually do start to see gas prices come down in September and October then pretty much flatten out in November and December. I think the trend will still be downward, but it won't be as dramatic as what we've been seeing."

The average price for a gallon of gas in North Carolina is $3.27.
