Have you ever spent minutes writing out an extensive list of groceries that you need to buy only to drive all the way to the store with the list sitting at home on the counter? No problem!
Next time you are on your way to shop for groceries, take a picture of your open refrigerator so you can see exactly what you have when you get there. This will keep you from buying something you don't need and will help you remember what you do need! It might also encourage you to clean out your refrigerator more often.
