I added a "Dinner for $5 or less" category. You don't have to take staple items into consideration when calculating cost. I think it's safe to assume that everyone has flour, sugar, milk, salt and pepper on hand at any given time. There are, of course, other staple items, but these are what I can think of right now. Anything that could require a trip to the store like meat or vegetables must be figured into the cost.
