Ample gasoline supplies and cheaper crude oil have led to lower prices at the pump this time of year.

Americans are paying, on average, $2.29 for a gallon of unleaded gasoline, according to a new report from AAA. That price has held steady for the past 12 days.

Gas prices have remained low for the past month or so with drivers saying about $1 per gallon on average over last year.

“Despite refineries going offline to conduct scheduled maintenance, there should still be more than enough gasoline to meet demand because people tend to drive less this time of year,” the report said.

The national average is expected to move even lower this winter, barring any major disruptions.

Gasoline could move below $2 per gallon for the first time since 2009 by the end of the year.
