We have had problems getting mason jars, lids, and bands all summer long here in our neck of the woods.
I did manage to order some on line a while back. I looked yesterday, and much of the on - line is out of stock or else wants 4 times the usual cost.
I wound up finding some pint jars for normal price and ordered 2 cases—they had a limit of 2.
If there’s an Ace Hardware anywhere near you they seem to be fairly good at getting canning lids.
This summer the local Runnings had pallets of canning jars.
I kept buying the wide mouth quarts so now have some extra cases I intend to use to pressure can more meat.
The lids that i find on occasion are so stinking expensive that now buying a case of jars is pretty cost effective. when you deduct out the $6.99 for a box of lids with bands, or $3.99 for the lids alone.
