The station posted the regular unleaded price on the sign out in front of the store for $4.09 a gallon, even though the pumps were only charging $3.76 a gallon.
Employees at the station later fixed the error. The price of diesel fuel was actually suppose to be $4.09.
Meanwhile, gasoline prices elsewhere around the Triangle are not far behind the $4 mark. The Exxon station on Six Forks Road in Raleigh is selling gas for $3.89 per gallon for regular.
Some analysts say drivers could easily see another $0.30 to $0.40 a gallon increase this year.
