I can't remember how much the plastic jars cost, but it seems the reason I have gone with mason jars was because of cost. I need to look into it more though because I think I spent a ton of money on jars this last year. I bought just a few at a time (by the case), but in the end I think I bought 4 cases. I also used them for canning blackberries and peaches. I made my own labels on my computer, and then everything looked uniform even though the contents were different.
