Now that gas is, for all intents and purposes, at $4 a gallon, we can begin the exercise of looking for the cheapest gas in town. Because hey, the difference between a $50 fill-up and a $55 fill-up is significant when we're all counting our pennies.

You can do this the old-fashioned way -- drive around until you note which gas stations have a line down the street, (and take your place at the end of it). Or you can do it the high-tech way and plug this URL at GasBuddy.com into your Blackberry.

Enter your city, state and zip code, and it comes up with a simple text list of the gas stations in your neighborhood, from cheapest to most expensive.

Maybe you can do this as you're waiting at the end of the long gas line this week, in preparation for your next fill-up. Far be it from me to suggest you take your eyes off the road while getting this information.

This is going to be a serious life-skill going forward. With that in mind, here are five more ways to easily find cheap gas. (courtesy of LifeClever)
