We started boycotting Loblaws and Shoppers Drug Mart in May like the movement said and haven't stopped since. We've been going out groceries at our local independent markets for produce, meats, fish, cheese, and other goods in bulk and getting the rest from Metro and Jean Coutu pharmacy. Metro aren't that much better but it's the lesser of two evils.
Honestly I can say we have saved a lot, especially on the bulk stuff for dry goods like nuts, flour, coffee, cereal and also dish soap, honey and even peanut butter.
