Wisconsin ? Dozens of drivers made a mad rush for cheap gas after a station employee accidentally changed the price to 33 cents a gallon.

An employee closing Trig’s Minocqua Shell for the night meant to drop the price of gas by 1 cent, but mistakenly dropped a nine from the $3.299 a gallon in the computer, making the price of gas .329 cents Monday night.

He left about 10 p.m., but drivers could still use their credit cards to buy gas.

Word of the bargain spread fast in the rural northern Wisconsin community, with 42 people buying 586 gallons of gas in an hour and 45 minutes. One person had pumped 27 gallons and two purchased 18 gallons.
