Are Gas Prices in Wisconsin ... Too Low?

Is it even possible for gas prices to be too low? Wisconsin says yes, and state authorities have stepped in to investigate after a month-long price war between local gas stations in Oconto County saw four stations offering prices as low as $3.39 a gallon this past week—nearly 50 cents less than other stations in the area, WBAY reports.

Wisconsin law says gas must be sold at a minimum 9% mark-up on the wholesale cost, to help protect smaller companies, reports Fox 11. Investigators from the Wisconsin Department of Agriculture, Trade, and Consumer Protection are now looking in to whether the prices offered by the Krist, Mobil, Shell, and BP stations were illegally low. Prices are now back up to at least $3.729, WBAY reports. (More gas prices stories.)
