As the price of gas goes up once again thanks to the uncertainty in the Middle East - a little research can go a long way towards saving you some money when you need to fill your tank.
There are a number of websites which track gasoline prices but the one I've found the most helpful is http://www.gasbuddy.com/. It's easy to use and it gives lots of results for easy comparison. (and NO I am not an affiliate and I won't get paid for sending you there!)
A few cents per gallon or litre adds up over time! Take some time to do some research and save yourself some of your hard earned dough!
