Hey Jim, it's almost always cheaper to buy foods, especially when on sale. However, when you make and can your own you know what went in it. It's usually way healthier and tastier, but just as important is the satisfaction of knowing that you produced it. I feel so gratified when I hear that 'pop' when the lid seals.anyone ever can chilli?and if so,is it cheaper to can chilli,or go with store bought?
