Find gas prices near you w/ Map Gas Prices: "

Map Gas Prices is a new service which combines gas price data with a Google Maps interface so that you can easily find out how much gas is going for near your area, and maybe help you find the cheapest gas stations. Gas prices have gone down quite a bit recently, but this is definitely very useful. You can also sign up for e-mail updates on gas prices if you want as well.
