Are first trip of the third month saved us $18.82 with simple coupon shopping at are local grocery store. As time goes on and we learn how to coupon shop we have started to restrict ourselves and try to purchase only coupon items.
When coupon shopping though it will save you money it is not always the best deal. Many item are lower priced and usually the store will give you a per ounce price when they are listed on the shelves.
