Saw this at Sam's Club today for $33. 00 for 4 96OZ bottles. Came home and read your thread and did some math, with the rebate that I just printed out from the Shell web site (thanks) it works out to 2 cents a gallon. Enough to treat my truck for 20,000 miles. I'll be going back to Sam's Club tomorrow to pick up a case.
Thanks
Denny
