BENTONVILLE, Arkansas -- Walmart announced on Thursday a 90-day rollback to save customers 10 cents a gallon on all gas and diesel at participating Murphy USA and Walmart gas stations in 18 states, but not in Oklahoma and Kansas.

Walmart says the reason Oklahoma is not on the list is because of state law. The company says state law bars Walmart from offering the 10-cent-a-gallon rollback in Oklahoma.

Update:  We've tracked down the law in question.  It's called the Unfair Sales Act.  [15 - 589.1-.11]

It is hereby declared that any advertising, offer to sell, or sale of any merchandise, either by retailers or wholesalers, at less than cost as defined in this act with the intent and purpose of inducing the purchase of other merchandise or of unfairly diverting trade from a competitor or otherwise injuring a competitor, impair and prevent fair competition, injure public welfare, are unfair competition and contrary to public policy and the policy of this act, where the result of such advertising, offer or sale is to tend to deceive any purchaser or prospective purchaser, or to substantially lessen competition, or to unreasonably restrain trade, or to tend to create a monopoly in any line of commerce.

The discount applies to gas purchases made when using a reloadable Walmart gift card, reloadable Walmart Money Card or Walmart credit card from June 29, 2011 through September 30, 2011.

Customers who use the Walmart family of cards to buy gas at participating gas stations will immediately save 10 cents a gallon on purchases right at the pump, with no other restrictions or requirements.
