When grocery shopping, make a list of what you need and stick to it. Make a list of what you toss away and don't buy it again. Don't try new foods at warehouse stores; instead, only buy bulk quantities of items you know your family frequently eats and loves. Avoid using coupons on food products you're unsure of, especially if it's a discount for multiples of one item. You're not saving money if you don't eat it. Don't be afraid of a half-empty fridge. If you need something, look for food delivery services in your area. Most of us, however, live near major supermarkets that are easy to get in and out of.
