I have a working theory that it is impossible to leave Costco without twice as many items as were on your list. You may walk in with the good intention of only purchasing almonds, greek yogurt, and a roast chicken, but inevitably chewing gum, toilet paper, and an 10 pound block of cheese end up in that oversized cart. The solution is simple: If you're going to impulse buy in bulk, be sure you get the good stuff...such as lean and mean ground buffalo.
