Hi,
I have been fortunate to be at the receiving end of plenty of jars donated to me by people who were retiring from canning. I also buy jars at church rummage sales for no more than 10 cents per jar. I have seen them marked at 25 and 50 cents, I advise I will buy for 10 cents; which when they get no other takers they accept.
The only jars I really run out of are jelly and occasionally pint. I then hope I can get a good deal at Odd Lots stores which sells Golden Harvest. Please note one company owns Ball, Kerr and Golden Harvest; they have no competition.
I buy my lids from Odd Lots, Woodmans just over the Wisconsin border or at Ace hardware when they go on sale around the 4th of July. I don't store my jars with rings on, you really don't want to do that, so I have a group which I use over-and-over for processing. I give fresh rings for jars given away as gifts. When I open a jar for home use, then I use a recycled screw lid from a mayonnaise jar. Please note the narrow mouth is substantially cheaper than the wide mouth, that I try to keep as much to the narrow mouth as possible.

Now that I have answered your question, I would like to know what you intend to store in these jars.
Thanks in advance!
