You make a great point of: penny wise, pound foolish. At first, shopping for the day can be like that. However, buying things like spices, oils, rice, etc, in bulk that do not go bad is a part of it. Ingredients you buy daily are exactly enough tomatoes, exactly enough ground turkey, just one small onion, etc, items that are priced per pound rather than cheaper in bulk.

I think that buying your perishables daily (if you can) can save you a lot of money and wasted food.
