Make a list with meals in mind and buy no more than you expect to use. 

Plan your meals
Make a meal plan each week. Plan for a “lazy night” where you eat out or eat up leftovers. Keep a running list of meals that your household enjoys. Try using the free Cozi app to keep track of your plans and lists.  

Shop at home first
Check your fridge, freezer and cupboards for any ingredients you already have before you go shopping. 

Stick to your plan
Make your shopping list based on your meal plan. Get a free meal planner and shopping list when you take the challenge. Include quantities on your shopping list to make sure you buy just what you need. Avoid packaged produce to control the amount of fruit and vegetables you buy.  

Other tips
Shop more often and buy less each trip so your food is fresher. Have a snack before you go to avoid impulse purchases. Check the bulk section for dried goods and spices and buy only what you need. Be careful with two-for-one deals on fresh items you can't store properly so you don't buy more than you will use. Plan your meals with ten easy steps by Save the Food.
