[Walmart] Engine Oil Sale @ Wal-Mart
Quaker State (5 L)- $ 11.44
Castrol (4 L) - $ 12.88
Looks like the exchange rate between USD/ CDN is hurting us, the Canadian buyers.
When the CDN was at par with USD, I remember the 'sale price' for Quaker State was $ 8.99.
BTW the 'new' regular price for Quaker State is near $ 20. Compare to before was around $ 15-16.
