16. Leave your children home when you shop
You may enjoy the social interaction of having your children with you when you shop, but there’s a hidden danger. While you’re preoccupied with reading ingredients or comparing prices, your little companions may be putting things into your shopping cart. These products may not reflect the best bargains the store has to offer. If you don’t notice this until you’re at the checkout stand, it’s probably too late to do anything about it. Next time leave the kids home or make a rule that only you can make food selections.
