One thing I found in short supply is canned pumpkin! I had decided to start getting stocked for the holidays in case it took a couple weeks to locate items.Hoarding causes short supplies . It looks like others beat you to it.
I assume it’s due to the aluminum shortage.Aluminum is not used for canning.
google aluminum can
That’ll teach me to post in the middle of the night when my brain is half asleep! LOL
When I mentioned it to a friend, she said people who make their own dog treats have been complaining about the shortage for awhile.
