If you sell your home canned goods- be it to friends or whatever- what do you charge? I find it hard to factor in all my costs as some of it comes to me for free (like apples from someone else's yard). I find the time to be the largest investment when it comes to gardening and preserving.
I ask because I want to be able to offer my excess to friends and family at a very low rate to just help off-set some of the expense and time and to have some sort of value placed on my goods. I use my goods as barter so a true "retail" price would be nice to have in mind as well.
