You need food to live. So you should have a plan on how to save money for food. Maybe Wal-mart is the best place to shop because they have stock. Maybe Costco is a better place. It doesn't matter, get coupons or whatever you can. There are many free things in life. Do you see surveys where they say they can choose winners for a $1000 gift card? You can do that online! Take whatever you can to succeed.
