Plan a menu for the week. Include all meals, snacks and beverages your family will need.
Take an inventory of the ingredients you already have in your pantry, refrigerator and freezer to determine which ingredients you will need to purchase. This is also a good time to remove expired items and take note of items that are nearly expired or almost empty.
Scan your grocery store's weekly ad for sales on items your family uses frequently, if desired. Non-perishable items can be purchased in bulk to save money. You can also print or clip coupons, which can be used alone or combined with grocery store sales.
Create a list of recipe ingredients and other items you will need to purchase. Shopping from a list reduces your chance of forgetting necessary items and having to return to the store later in the week.
Clip any coupons you plan on using to your shopping list with a paper clip or carry them with you in a small coupon organizer. This will help you remember to take the coupons to the grocery store with you and make them easier to find at checkout.
