What are some good ways to control costs for groceries?
Cooking cheaply is time consuming. We cook cheaply, but we take more time to do it. May be hard for a busy family.  If you cook everything from scratch, it's usually a lot cheaper. Also pre-planning meals helps.  If you can coordinate your ingredients, you can save money.  Saving money takes time and practice. I find that when we're rushed, we waste a lot more food than when we properly take the time required.
