Found the 5qt (1 gal) jugs of 5w30 valvoline semi-synthetic on clearance at my local walmart (22030) for $7. They were in their usual motor oil location. Excellent price for 5 qt jugs. Only this weight and type was on clearance. Link is for reference to the online listing for the item, which shows full price. Clearance was IN-STORE, so YMMV. My Walmart had 8 jugs on the shelf. Bought two jugs, rang up at $7 each.
