Buy: Verka organic yogurt
If you are willing to spend a little extra, you can buy a 64-ounce tub of Verka organic yogurt rather than buying a 16-ounce tub at the supermarket. Contrary to what you may think, this item can stay on the shelf for a long time and taste delicious. This is truly the best yogurt choice offered by Costco.
Skip: Las Fortunitas tortilla chips
If you manage to find these Las Fortunitas chips at Costco, you should run in the opposite direction because the bag will never be finished regardless. Not only will you be throwing these out, but you will also be rating them as a B-minus with those hydrogenated oils.
