I have canned food before and I can tell you that it is neither easy nor inexpensive. But it is worth it to do it.

The initial outlay of money is substantial with buying canning jars and lids, a pressure canner and all the trappings needed to do the job. And it is a hot miserable job in the summertime where I live.

Best thing is to freeze what you intend to can during summer and when it's cooler/colder weather, can it then.
