The one in Murray, KY.
I had to come home to get front brake pads and rotors replaced. I went to Walmart for a couple of things and was near the automotive department and they had all these Mobil 1 jugs on an end-display. Thought I was seeing things at first, but they only had one jug of 0W-40 on the display (basically, one jug of each flavor). Checked where they keep the oil normally and sure enough, there it was. Five jugs of it. They also had a single quart bottle, which that particular Walmart has never stocked before. I don't recall what they price of it was, though. Was too excited to find it in jugs, I guess.
