It takes very little work to make your own stock; mostly it is a matter of being at home for the several hours it takes to cook. A flavorful money saver that is practically fat- and salt-free, homemade stock can be frozen in small quantities and used as needed.
Chicken backs and necks are available at most supermarkets. If you don't see them, ask the butcher to set aside some for you. I also make stock from the bones of roasted chicken or turkey.
