I’ve found canning lids almost everywhere.
Wegmans has them.
The local Mennonite store has them.
You may want to check out Tattler reusable canning jar lids.
I have some applesauce from 2011 that I used the lids on, and I wanted to see how long they would last.
Nine years and the applesauce is still good.
We don’t have Wegmans but we do have an Amish store which is where I buy a lot of stuff - like they had celery seed which another thing they don’t have in stores here. I never even thought of them for canning lids, I’ll have to try there.
