Our Big Lots had several "canning kits" this past week, a pickle kit, salsa kit, spaghetti sauce kit, etc...I have found the jars at our wal-mart (super center) and at our Albertson's grocery store. I love canning, I usually do apple butter, pear honey, fig jams, and pickles. Last year I got more adventurous and did habenero peach salsa, raspberry habanero jam, spicy pickles, and lots of things with figs (my aunt has several fig trees)
Good Luck.
PS: your homemade goodies make great holiday gifts!
