An Alabama pipeline spill earlier this month has caused spotty outages and rising prices at gas stations in metro Atlanta.

The pipeline spill has even caused Gov. Nathan Deal to sign an executive order banning price gouging at the pump.

Even if you're staying close to home, remember these tips to help you save on the cost of gas:

Know where to go. Use apps like Gas Buddy to help you find the least expensive gas when you need it. Search your ZIP code to get up-to-the minute information on who has the cheapest gas.

Look for deals. Retailers including Wal-Mart and BJ's are known for running promotional discounts on gas. Loyalty programs such as those offered by Kroger and BP, help you save on gas any time by letting you accumulate points you can redeem for gas credits. Kroger offers periodic promotions that help you earn gas credits faster.

Pay cash. At my local Shell station, there used to be a sign posted indicating a surcharge for using credit cards at the pump. The signs disappeared, but I'm pretty sure the surcharge didn't. There are no laws on how and when surcharges must be disclosed, which makes it hard to know what you're dealing with. Stations can avoid any issues by offering a "discount" on cash purchases. Get it?

Fill up at the right time. Traditionally, it is cheaper to get gas on a weekday morning instead of the weekend or the evening. Prices typcially go up for the weekend on Thursday morning, so fill 'er up on Wednesday for the weekend.

Keep your car in shape. You can reduce the amount of gas you burn by keeping up with the proper maintenance on your car. Be sure you have air in your tires, check your alignment regularly and keep excess junk out of your trunk since a heavier car uses more gas.

Try alternate transportation. If all else fails, reduce the amount of time you drive. Carpool with friends. Take public transportation. Ride your bike or walk.
