Ok, Walmart isn’t my favorite store… but the canning jars that we got from them were literally a quarter of the price (fine, a bit less than a quarter) of that what we could have gotten from Amazon.
One flat (a dozen) of the quart jars was $56.00 from Amazon. We got three plus a slew of other stuff for less. (And this isn’t counting tax which we’d have to pay with Amazon as well)
There’s been a run on canning supplies and people are just being opportunistic about this stuff.
