The national average price for a gallon of regular gas has crossed the $4 mark, $1 more than just one month ago. The price now sits at $4.06 a gallon, according to the latest data gathered from AAA. That’s up from $2.98 just a month ago, with the conflict in the Middle East sending crude oil prices skyrocketing. However, the average also fails to reflect the significant price variation across states.
