Gas prices are vacillating, depending upon which market you are considering.
The average price of gasoline is up 7-cents over the past two weeks.
The Lundberg Survey says it's now $1.84 a gallon.
But industry analyst Trilby Lundberg says despite the increase, the price is 70 cents per gallon cheaper than a year ago.
In Tulsa, gas prices increased by 20-cents last week, but are down a few pennies on Monday.
Most Quiktrips and Phillips stations were up to $1.69 last week.
Lundberg says the moderate price hike is due to growing demand for gasoline across the nation and higher crude oil prices.
