Buy: Verka organic yogurt
You can get a 64-unce Verka tub of organic yogurt for only a little more than you would pay for a 16-ounce tub from the grocery store. It is surprising to hear that the product boasts a long shelf life and a taste comparable to whole-milk products. The yogurt got a good rating from the Cornucopia Institute, an agency that promotes family farming. There are other Costco yogurt options, but this one is the best.

Skip: Las Fortunitas tortilla chips
If your local Costco sells Las Fortunitas chips, which come in a container the size of a garbage bag, ignore them. We are not saying this because of the price or the taste. The bag is less than $6, which is a great price, and the chips are great. However, we think that you should skip them since you will be unable to finish it. You can buy them for a party, but we are sure that your guests can only finish half of this 5-pound bag. Aside from that, Fooducate gave the product a B-minus rating thanks to hydrogenated oils.
