Gas prices hit three-year high and are expected to keep rising

If the higher prices pinch your budget or affect your vacation plans, there are ways to save money on gas.

For starters, shop around.

Depending on where you live, there can be big price swings between gas stations. For instance, a recent review of the Los Angeles area found a difference of about $1 per gallon between the highest- and lowest-price stations, DeHaan said.

While the difference in price per gallon may only be a few pennies, it still adds up.

“Even if it’s a difference of a nickel or dime, that could become a couple hundred dollars in savings,” DeHaan said.
