We have a Rural King here (think Tractor Supply Company, which we also have). The website shows a dozen Ball jars are about $9-$11 a dozen; most sizes are shown in stock at my local store.
That’s about what they used to be at my local TSC and Ace Hardware. They have stayed sold out 🙄
I’ll check out our Tractor Supply. I never bought anything there but it’s always good to know where the suppliers. I think I’ll go to Save-A-Lot again tomorrow, now I did buy a bunch of Lids there. They were pretty cheap if you bought the whole case.
