South Dakota’s Gas Price Average at Lowest Point in Six Weeks.

Pump prices nationwide have now fallen for 30 straight days – the longest streak since August/September of last year – and are at their lowest mark for this date since 2004. Today’s national average for regular gasoline is $2.23 per gallon, four cents less than a week ago, fifteen cents below the price one month ago, and 53 cents cheaper than one year ago. Approximately a quarter of gas stations nationwide – 25,000 – are now selling gasoline for less than $2.

“Today, for the first time since June 1, South Dakota’s statewide average for regular gasoline hit $2.31 per gallon,” said Marilyn Buskohl, spokeswoman for AAA South Dakota. “However, if you’re traveling in or through Sioux Falls, you might want to fill-up there for $2.10 per gallon. The city wide average for Rapid City is 32 cents higher according to GasPrices.AAA.com.”
