They were practically giving it away. Two gas stations in Northwest Ohio lower their prices for gasoline to practically nothing.

FOX's Joe Chiaro reports:

It all started early Sunday at the pilot travel center in Toledo when a computer glitch changed gasoline prices to just 49 cents a gallon.

Less than two hours later, prices dropped to 19 cents a gallon! Just across the street is a Circle K store. They saw the low gas price and to stay competitive dropped their price to 17 cents a gallon.

It didn't take long for drivers to notice:

(Man) "I just filled my whole gas tank from dead empty for 26 cents, so..."

One customer even had a receipt after buying gas for one penny a gallon. The price war lasted for at least three hours.
