Mapgasprices
Mapgasprices is a slick use of Google Maps which lets you look not only at the national low, national average and national high for a gallon of gas, but also lets you put in your location and view gas stations nearest you. Just click on the markers on the map to see what the prices are, or refer to the right-hand column and click on the gas price you want to view and you will get a map to the station that offers that price.
