One Toronto grocery store is making waves for its dirt-cheap prices, but some locals want to keep this hidden gem, hidden. "Crazy bc these EXACT brands of fruit and veg r at loblaws for 3-5x the prices," one person comments. On the other hand, though others were quick to express their worries about Kai Wei Supermarket getting too well-known. Luckily for budget-conscious shoppers in the city, Kai Wei isn't the only place where you can find great deals on produce. Kai Wei Supermarket is located at 253 Spadina Ave.
