SOUTH BEND — Gas price has hit another record — it is now $3.34 a gallon nationally. That's 55 cents higher than a year ago.

People are looking for ways to save as much money as possible when fueling up.

Many gas stations are offering credit cards that they say will save you at the pump. It may sound good, but some say these cards could cost you.

Laura Dickerson, who commutes to Gary for school, says the gas gauge hurts.

“It's getting ridiculously high!” she told WSBT News.

It's no surprise with prices soaring — gas cards seem to popping up at the pumps. One offers a 5 percent rebate on every dollar you spend on fuel.

But Dr. Grant Black, an economics professor at IUSB, says ‘buyer beware.’

"You need to pay attention for the length of time the rebate lasts,” he explained. “Sometimes it might only last for up to a year."

Some say these cards, which tend to have higher interest rates, could end up costing you more.

"Open up another credit account and get yourself into more debt,” said Charlene Anthony of South Bend. “You just pay and try to budget and limit your driving and take it from there.”

Dr. Black says with gas prices only going up, conserving is the way to go.

"Can you carpool, can you consolidate to one vehicle, and can you take turns using the car?” he urges consumers to ask themselves.

Dickerson says the gas card is just a small fix to a big problem.

"I wanted to buy a bigger SUV when I was done with school, but with gas prices I don’t want to!” she said. “I'll just stay with what I have.”

Black recommends reading all of the fine print before applying for a gas card and if you have one try to pay off your balance every month.
