Here's a tip on how to save money on gasoline:
Find cheaper gas: Compare gasoline prices at GasBuddy.com, GasPriceWatch.com and Gasprices.mapquest.com. Of course, you don't want to drive far out of your way to save a few pennies. Savings will be lost traveling to a distant service station.
Billshrink.com will send you an email alerting you to the lowest-price gas on your commute.
Gas price information also is available via smartphone apps such as Gas Buddy and AAA's TripTik Mobile.
