South Dakota drivers might be taking note of a change at the pump. Gas prices are down at least 30 cents from last month.
On average, you'll find a regular gallon of gas costs $3.20 right now. Last week, prices were around $3.30.
Officials with AAA South Dakota expect prices to continue to drop in the coming months. They say more than enough supply, flat demand and cheaper winter-blend gas mean drivers are likely to pay less to fill their tanks.
AAA spokeswoman Marilyn Buskohl says prices could even fall to $3.19 by Christmas.
Today's national average price for a regular gallon of gas is $3.35.
