You may have noticed a higher bill the past few days while paying at the pump.

That's because almost overnight most gas stations in the area raised its prices about 10 cents per gallon, going from $1.99 to $2.09 a gallon.

A Triple A spokesperson says the price hike is because of an oil shortage.

He also says that because prices usually are a few weeks behind the market, prices may go up another $.05 to $.10 following the increased value of a barrel of oil.

"It seems like it happens overnight but there's lots of things that are happening within the market that generally drives those prices up, sooner or later retailers have to pass their additional costs onto the consumer and that's what we're seeing now," says Gene LaDoucer a spokesperson for AAA.

According to Gasbuddy.com the cheapest local gallon of gas can be found the Cenex at 2921 N Broadway for $1.96.

LaDoucer says he expects gas to fall below $2.00 a gallon again by Halloween.
