Shopping when you know you need food but you're not sure what, or if you're just plain hungry, usually ends up in spending more than necessary. It can also lead to multiple trips to the store when you realize you've forgotten something. One of the best ways to save on groceries is to come up with a weekly menu with an ingredient list. Review weekly sales flyers to see what's on special for the week and use those items to plan your menu. Most of all, learning to cook can save you additional dollars by curtailing eating out. Not to mention, it's much healthier than fast food.
