Cheap Gas?

Not really cheap gas it is only going up. I was looking for Gas Stations in Downtown St. Louis that I wouldn't get mugged at. I found this site and really like the map and some other features that show local gas station prices.

Looks like Sam's and Costco are the best bets, obviously you have to pay extra to become a member. Costco near me was $3.35 where the average was $3.48
