go to wic (womens infents and childrens) there is normally one in every state and they do provide formula coupons that you use at stores its normally very easy to sign up and they give things to kids up to 5 years (cereals fruits veggies milk juice eggs peanut butter bread) all in coupons and each kid gets 4 coupons a month with different things on it. it does not cost you a thing to get on it just make an appointmetn and bring what they ask you to for the first appointment
