Of course. There are ALWAYS rules. And I'll put them up as I think of them. For now, here are some rules:
Rule No. 1) This is a subjective list. That means it's based on my likes and dislikes and what I think is a good deal. If I don't include something on the list that seems to be a good deal, I'll explain why I didn't include it. That leads to
Rule No. 2) If you know of a deal that I don't know of, please please PLEASE tell me. Preferably before I hit the grocery store.
Rule No. 3) Some rules are meant to be broken. You'll see what rules those are as we go along.
Rule No. 4) The $50 for the stockpile is money you'd spend aside from your normal grocery spending. The idea is that eventually, you won't be spending all that much on the 'normal' groceries because you'll already have most of what you need in your refrigerator and your freezer and in your pantry.
