Costco

The summer travel season is finally in full swing. While gas prices remain high, many major retailers are taking steps to cut costs for disgruntled drivers. Wal-Mart is leading the charge, reducing their fuel prices by 10 cents per gallon for the summer months. The retail giant will offer discounted prices at gas stations in 18 states until September 30. Many other stores have followed suit with their own deals. Here's a list of other major merchants helping Americans save at the pump this summer.

CVS
The drug store chain is offering a free $10 gas gift card to ExtraCare Rewards members when they purchase $30 worth of select products. The promotion runs through August 28, so there's still plenty of time to cash in.

Kroger and Shell
The grocery chain has been offering discounted gas for quite awhile now, but their partnership with Shell has really turned up the savings. With 100 points on your rewards card, you'll get 10 cents off per gallon on a fill up at both Kroger and Shell stations. If you're not satisfied with that discount, Kroger also offers $1 off per gallon when you earn 1,000 points on your rewards card.

Kellogg's
Do you eat a bowl of cereal every morning for breakfast? If so, you're well on your way to saving on fuel. When you collect 10 UPCs from cereal boxes and mail them in, Kellogg's will send you a $10 prepaid gas card. Submissions must be received by December 31 and there's a limit of five cards per household. Read more
