Wisconsin gas station accidentally sells gas for 28 cents a gallon

A price mistake at a Wisconsin gas station had customers flocking to the pumps.

There were so many people at the business after hours, police were called to check things out. What police found was gasoline for only 28 cents a gallon.

According to police, a clerk put in the wrong price before they closed for the night, around 9 p.m.

The price of mid-grade was supposed to cost $2.89 per gallon, but somehow it only cost people 28 cents per gallon to fill up.

Word spread fast, and by the time police got there a couple of hours later, at least 100 people had taken advantage of the cheap gas, all filling up their tanks for less than $5.

The gas station lost out on about $3,500.

According to the Department of Energy, gas hasn't been 28 cents since the 1950s.
