It is easier to buy a box of macaroni and cheese, but is it more economical?
A large box of macaroni and a block of cheese will make more servings for your family than one box of prepared macaroni and cheese.
The next time you go shopping and pick up a box or bag of an already prepared item, ask yourself if you can make that at home for less.
If you can, then put that item back in favor of less expensive staples.
