What The Numbers Mean
The data shows that sale prices drive many of the lowest costs. For example, Carnation Evaporated Milk was $1.52 at Walmart on sale, compared to $4.00 at Food Basics. Similarly, Yoplait Source Yogurt was $2.97 at Walmart versus $7.49 at Sobeys.
Even big-box stores like Costco aren't always the cheapest on name brands. We saw Drinkable Yogurt for $3.79 at Food Basics but $10.99 at Costco (also on sale, down from $13.99). The same applied to Kellogg's Frosted Flakes, which was $2.49 at Food Basics and $6.99 at Costco (also on sale, down from $9.79).
Bottom Line
If you want the best price on specific items like evaporated milk or yogurt, Walmart is currently leading in Mississauga. However, many of these lowest prices are temporary sales, so check the flyer before you go. For produce like green onions, discount chains like No Frills and Giant are beating out premium grocers.
