There's way more than that. Those are just the "featured brands" (ie the ones that paid extra to be featured at the top of the list). If you scroll down the list, you can see others (Foodora, Indigo, Ladndmark Cinemas, M&M Food Market, Roots, Fairmont, Well.caAldo, Oliver & Bonacini, Shack Shine are just the few that showed up at the top of my list after the featured brands). I earn a buck a month in cashback just from my wife's Weight Watchers membership. Lol.
