JACKSON, Miss.--If you fill up today in Mississippi, you'll likely pay very close to the national average. That's unusual because the Magnolia State has thus far been able to keep a pretty good gap between the two averages.

On average, you're paying $3.63 today. The national average for a gallon of regular is $3.71.

Gasbuddy.com analyst Greg Lakoski says factors for the high prices include rising crude oil prices and refinery closings. He also had some advice for Mississippians who may want to go a little further to get cheaper fuel.

"If you're in a very affluent neighborhood, chances are those stations are charging what they think the market will bear," he said. In other words, if you're buying gas in a nice neighborhood, they're probably charging more.

"Getting your gas at the station that's closest to the highway you take to get to the office, if that's your habit, is probably gonna cost you more than driving to another station."

Prices were still rising Wednesday.
