It was 100% accidental, but I found a local supplier of jelly jars and lids!http://www.containerandpackaging.com/
Container & Packaging Supply, Inc. is out of Eagle, Idaho, but their Fulfillment Center is . . . guess where? Bluegrass Industrial Park in Louisville, KY.
Wish me luck. I ordered a full gross of jars and will pick them up (no shipping!) in a couple of days.
