BENTONVILLE, Ark. - This week, Walmart announced a 90-day Rollback at the pump to give customers a savings of 10 cents a gallon at participating Murphy USA and Walmart gas stations. The discount applies to gas purchases made when using a reloadable Walmart gift card, reloadable Walmart MoneyCard or Walmart credit card from June 29 through September 30, 2011.

"Our customers have told us that high gas prices are a top budget concern, nearly as large an expense to their households as food and groceries," said Stephen Quinn, chief marketing officer, in a press release. "We listen to our customers and because we know they are feeling squeezed by gas prices, we??re implementing this gas Rollback to help them save, especially during high travel summer months."

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.

"It??s important to us that we extend this offer to everyone, not just Walmart customers shopping in our stores, without requiring any other type of purchase," said Quinn. "Our goal is to make it easy for everyone to save and live better, and we think this gas program is leading in the market because it doesn??t require any additional purchase, loyalty card or other restrictions."

States with participating gas stations include Georgia, Idaho, Illinois, Indiana, Iowa, Kentucky, Louisiana, Michigan, Mississippi, Missouri, New Mexico, North Carolina, Ohio, South Carolina, Tennessee, Texas and Virginia.
