For 90 days, Wal-Mart will give you the chance to save a dime per gallon when you fill up at one of their pumps or at a Murphy USA station.

Whether you use diesel or regular gasoline, you can take part in the dime savings between June 29th and September 30th when you use a reloadable Wal-Mart MoneyCard, reloadable Wal-Mart gift card, or Wal-Mart credit card. Sure, ten cents may not seem like a whole lot when you're looking at a gallon of gas costing just under four bucks--but it adds up. 

Get more info on the deal at 24/7 Wall St.'s report here, and check to see where the closest Wal-Mart gas station is to you on this handy-dandy map.
