Skip: Las Fortunitas tortilla chips
If the Costco near you sells Las Fortunitas chips – those that come in a bag the size of a garbage bag – skip them. This isn’t because of the price. The bag costs less than $6, which is an incredible deal. It’s not the taste either – these chips are good. It’s because you most likely will never finish the whole bag. Even if you buy them for a party, you’re probably going to have half of the 5-pound bag left-over. On top of that, Fooducate gave these chips a B-minus rating since they contain hydrogenated oils.
Buy: Kerrygold butter
There are several brands of butter sold at Costco, and the organic Kirkland brand is one of them. If you want high-quality butter, foodies have said to prefer Kerrygold. It’s made with milk from grass-fed cows.
