Just went to Walmart last night and found a few different oils on clearance
Valvoline Synpower 0w20 was $3.50/qt
Various Pennzoil Platinum @ $3.25/qt plus eligible for $2/qt MIR
Pennzoil Platinum (PP) 10w30
PP High Mileage 5w30
PP High Mileage 5w20
Pretty sure I also saw some Ultra Platinum 5w20, but somehow missed the UPC in my pics I took.
FYI, the Walmart that was clearancing these oils is the only location around without a Tire/Lube center. It looked like they were REALLY cutting back on stock - not even full ranges of one brand, just the one-offs they can't cover with supertech (0w40 euro oil, etc)
Also, $2 per quart MIR is still active until 12/31/17
Alternatively, its been posted here before, but Amazon STILL has 5qt containers of PP for $25 before $4 instant coupon and $10 MIR.
You can't beat good synthetic oil at $1.25 or $2.20/qt after MIR
On my tablet so no hyperlinks... Sorry
Edit - fixed brickseek skus and links. now take those thumbs down and shove em'.
