Skip: Las Fortunitas tortilla chips
We agree that the Las Fortunitas chips taste great. However, we want you to know that it is not a good idea to buy the huge packs that you can get at Costco. Trust us, it will take you forever to finish the whole bag. Fooducate has also rated it B-minus thanks to its hydrogenated oils. You have been warned.
Buy: Kerrygold butter
There are a lot of butter brands available at Costco. You are going to find the organic Kirkland one among these products. However, you might want to splurge a little more on Kerrygold if you are looking for quality. In case you did not know, this brand uses milk that came from grass-fed cows!
