The thing no one tells you about canning is that once you start, jars and fruit and vegetables just sort of turn up in your life. Friends will give you their old jars (especially when you return them full of jam) your co-worker will let you know about the guy down the street with a prolific fig tree he can't keep up with and your brother will 'accidentally' buy a large bag of very ripe peaches and turn up at your door wondering if you'd like to make them into jam and give him half of the finished product. Once you have the basic equipment it's sort of self sustaining. This year I came home from work one day in July and there were 8 pounds of sour cherries on my doorstep with no note. I have no clue who dropped them off but they made amazing jam (and pie). Can on!
