We need to do a Costco run too in the next day or two. It's great to know that we're not the only ones who buy the exact same thing every single time. haha. Every single time we do a Costco run, the list includes: bell peppers, mushrooms, bread, sandwich meat, and berries. The only flexibility comes with whether or not we get cereal, chicken, and onions. Our Safeway lists are similarly set in stone. I always just figured it was a sign that we're going on 60 years old. It's good to know we're not alone. :D
