My dad would drive miles away just to get cheaper gas. He knew it defeated the purpose, but it was the principle of the thing. He supported cheaper stations, and was amongst the early adopters of self serve along with its lower prices. GasPriceWatch.com tracks the prices at gas stations, and of heating oil (and marinas, coming soon) in the U.S. and Canada through the help of volunteer spotters. You can search on zip/postal code and find stations near you and compare prices. Prices are color coded so you know how old they are. And maybe you’d like to sign up to be a spotter yourself. I always try to buy gas at the cheapest place I can find, but I don’t go overboard about it. My dad has also loosened up. Time is money, or, more importantly when you’re older, time is, well, time.
