Just goes to show how inflated the prices of brand names can be when a large retailer can buy a big manufacturer's oil, label it Walmart brand or Advance brand full synthetic and sell it for 4.99/qt and make a profit..
That means said big manufacturer sold it to them for less than that and still made a profit, when just because the label says Mobil 1 on it, the same oil in the bottle is suddenly 8.99/qt, lol
