I was watching the Today show the other day and they talked about this website so I thought I'd check it out. Have you heard of GasBuddy.com? You can go to their website and download their app to your smartphone. Log into it while you're out driving and it will use your location to tell you where is the cheapest place nearby to buy gas. With gas at over $4 a gallon even a 30 cent per gallon saving is significant. Click here to check them out.
