Canning Supplies, this time of year you may be able to find a few good deals on canning supplies. A pressure canner if you can afford one, if not you may be able to work with someone who has one and trade work or food for the use of one. A water bath canner these are not nearly as expensive but a very limited as to what you can can with them, A very good place to start if just starting out though. Jars and lids seems you can never have to many of these.
