coupons/samples

I've been doing some research on where to find coupons! Coupons.com, newspaper & you can even email the companies of the products you use daily and they will send you coupons In the mail! I shop at HEB mostly and I'm looking for deals in our area because most of the stores that double coupons are in bigger town or other states that we don't have!! Heb has meal deal were you buy a item and get others free, also in-store coupons! Only buy what you use and stock up when it's on-sale, Thoses are Two of my tips on saving more. Why pay so much on food when you can use coupons!!'
