Come to Kanada if you want to get gouged. Early this spring both Walmart and Canadian Tire were $49.99 for a 5L jug of Castrol Edge (black jug). Costco was between 37.99 and 43.99. Costco is the only place Ive actually seen where prices actually fluctuate DOWN. Early summer Walmart went to 52.99 and Canadian Tire went to 63.99. A couple days ago Walmart was 59.99 and Rip Off Tire is now 72.99. Costco is 48.99 and thats where I bought my winter change of 0/20. Kanadian Tire has become a ripoff. They have many store across Canada so im sure they have “purchasing power” because of quantities. Just for the heck of it I checked out Peavy Mart and the same jug was 84.99!! If youre unfamiliar they are a farm supply store woth 89 stores.
