If you are looking to save money on gas, Wal-Mart has an offer for you in nearly two dozen states.

Gas at wholesale is dropping after a run-up in price leading up to Hurricane/Tropical Storm Isaac. There has been no damage to drilling rigs or refineries in the Gulf Coast area to speak of. So day by day, more production is coming back online. Yet the price at retail still lags behind wholesale, as it always does.

Wal-Mart is offering a discount of 15 cents/gallon all fall long through Dec. 24 at any Wal-Mart gas station if you use a Wal-Mart money card or credit card. (A 10 cent/gallon discount applies if you want to use a gift card instead.)

Participating states include Virginia, Texas, Tennessee, South Carolina, Ohio, North Carolina, New Mexico, Mississippi, Missouri, Illinois, Georgia, and Arkansas, among others.

To find a participating store near you, search by zip code on WalMart.com.

Florida and Alabama are participating states, but the discount may not be 10 cents or 15 cents in those states for an unfortunate reason. What happened is the anti-free market lobbyists got laws passed in those states because they believe such promotions would hurt oil company gas stations.

The big, bad oil companies are so weak they cannot compete against a discounter?! So at the states’ behest, the oil companies got these laws passed restricting the free market. I asked the governor of Florida why he is opposed to the free market, but that is a political discussion for a political talk show.

For now, just save that money at the gas pump if you can in your state!
