At some Michigan gas stations on Sunday, drivers could buy a gallon of gas for a couple of quarters – and still get change back.

The uber low prices – recorded as low as 47 cents at one station in Houghton Lake – appeared to be the result of a local price war. Photographs of several stations showed prices below $1, FOX2 reported.

By Monday morning the super savings appeared to be over. Prices were still much lower than average, but the lowest across the state were above $1.30, according to Gas Buddy.

Rough driving conditions in the area of several stations didn’t deter customers on Sunday and police had to help direct traffic due to long gas lines, 9&10News reported.

The last time the statewide average gas price dipped below $1.75 was in January 2009.

U.S. oil prices continued their historic slide Monday, slipping below $30 per gallon.
