WILMINGTON, N.C. —  Traffic was backed up and police were called to control the crowd after a Wilmington gas station accidentally set the pump price at 35 cents a gallon.

The Wilmington Star-News reported Friday that hundreds of drivers flooded a BP station for the cheap gas after the price dropped around 9 a.m. Thursday.

Station employee Shane Weller said the price for premium gasoline was supposed to be $3.35 a gallon. He complained that customers paid the cheaper price all day without saying a word.

It was all the extra traffic that led station employees to the mistake around 6 p.m. They found it after calling their district manager, looking for permission to changing the price as a way of stemming the flow of customers.
