I find that Loblaws are much more expensive than most other grocers when comparing the same product. In my area, Walmart usually has the best prices.
I think it depends on which of their brands you use. No Frills is usually pretty cheap, while Loblaws or Fortino's are more expensive for the same items.
As for the price of chips or other items, the companies are using inflation as cover to jack up prices and increase margins. They basically brag about it on conference calls with analysts. Yes, they are experiencing higher costs for materials, packaging and transportation, but the price hikes are higher than those new costs. And....will the prices go down once the supply chain issues are resolved? Fuck no.
Now, I'm shocked Loblaw is playing hardball. I mean, usually they just pass the increase onto shoppers. The price hike must be egregious, or Loblaw doesn't want to buy inventory that shoppers might balk at paying for.
