(KCEN) -- If you've done a double-take at the pump, you're not alone. Gas prices are soaring.
The Lundberg Survey found the average price of a gallon of gas has jumped nearly 25 cents in two weeks.
The national average price for a gallon of regular is now $3.59.
It's the biggest two-week jump in nearly two years.
Lundberg blames a rise in wholesale prices for the jump.
