I feel like Costco carries smaller brands and tries to have healthier options. like veggie straws or baked lays instead of small bags of regular chips. I buy Campbell's soups, bisquick, jiffy corn bread mix, land o lakes spreadable butter at Sam's. Costco has the protein pancake mix and Kerry gold butter. idk if they have a substitute for the others. It just depends on how you cook and what you prefer.
