Where the cheapest Gas is

This is pretty nifty. Just enter your zip code in the site below, and it tells you which gas stations have the cheapest prices (and the highest) on gasoline in your zip code area. It's updated every evening. Also if you are traveling it will help, too as gas is really expensive in some parts of the US.

I use a similar site for local prices:
