If you have an iPhone or Android device, apps like GasBuddy and Cheap GasĀ use the GPS feature on your phone to generate a list of gas stations near you, along with prices. If you don’t have a smartphone, you can also check GasBuddy.com before heading out for your next fill-up.
The caveat: Prices are reported by users, so they may not be up to date if you’re in a sparsely populated location.
