That's what Kelly Joosten and dozens of other motorists paid at a Citgo station Monday. The sign advertised $3.43 for a gallon of premium fuel, but the pump cost read $0.349 a gallon.
"That was amazing," said Joosten, who normally spends about $100 to fill up her 1998 Ford Expedition.
Joosten proudly showed off her receipt for 25.36 gallons at $8.85. She said she saw other motorists filling gas cans, too, at the discounted price.
Station owner JP Raval says the attendant on duty couldn't figure out why the station was suddenly so busy.
Raval estimated 30 to 40 customers fueled up at the incorrect price - between 200 and 300 gallons worth - for about 90 minutes.
"People kept coming, so fast," Raval said. "Everything was crowded; it was like a fairground."
