Believe it or not, gas keeps getting cheaper in South Dakota and across the country.

The average price for a gallon of regular unleaded gas in the state is $2.36, according to AAA. Last week it was $2.42 per gallon. One month ago it was $2.48, but a year ago it was only $2.15.

“Gas prices are pushing cheaper for two reasons. Crude oil prices are $10 less a barrel than one month ago and U.S. gasoline stocks sit at an all-time record high,” said Marilyn Buskohl, AAA spokesperson. “Cheaper crude and healthy stock levels mean motorists can expect prices to continue to decline this month.”
