MADISON, Wis. -- Gas could reach $4 a gallon and prices for teen favorites like pizza and soda have all climbed, squeezing the amount of cash teenagers can spend elsewhere.

When teenagers get a license, it means not always being dependant on parents. But these days for teens, that freedom comes at a cost many can't afford.

Shelby Demos, a junior at Parker High School, said climbing gas prices are a concern.

"I'm going to probably have to get a job," Demos said. "I don't drive that much anymore because my parents only give me a certain amount of gas money per week."

While teens are spending more on gas, they're spending less everywhere else. Last month, sales at major teen retailers dropped 8 percent. Marketwatch.com reported that retailers Abercrombie and Fitch, American Eagle and Pacific Sunwear all experienced reduced sales.

"It takes my saving money away. I would save more money and put it into the bank, but instead I'm taking it out and putting it into gas," said Zach Cramer, a high school junior.

Cramer said that much of what he earns goes toward paying for gas.

"(A gallon of gas at) $3.30 is kind of a lot. I remember, like four months ago, I hadn't paid more than $3.07 ever. So, 25 cents more is a lot," Cramer said.

For now, teens who spoke with WISC-TV said they'll deal with paying for gas at the pump, but some said they'll really cut back if prices continue to rise.

"Probably when it gets close to $4, I might not drive so much," said Erica Heitsman, a junior at Parker High School.

Gas has been around $3 a gallon ever since most teens have been old enough to drive, so it's not as much of a shock to them. But they said that doesn't mean it's any easier for them to buy the things the feel they need.
