New Jersey drivers are getting a bit of relief at the pump as gas prices continue to edge lower.

GasBuddy says two locations in the state are currently selling regular gasoline for less than $4 a gallon. The Costco in East Hanover and the BJ's in Whippany are both charging $3.99 per gallon.

At the Costco in Edison, regular gas was selling for $4.22 per gallon Wednesday morning. While drivers need memberships to take advantage of those prices, it is a sign that gas costs have come down at least slightly.

Experts say shopping around can make a big difference for drivers looking to save money, as prices can vary significantly from station to station.

Even for motorists who do not have the flexibility to seek out the cheapest stations, gas prices have fallen slightly in recent weeks.
