Walmart has Mobil 1 Extended Performance at a great price, and is now apparently offering free 2-day shipping. Remember, Walmart purchases are accepted for this year's mail-in-rebate offer, but Amazon is not!

I ordered 2 jugs yesterday, along with 2 filters from Rockauto to max out my rebate at $30.
