The store where I buy this food has instituted a curbside pickup policy - no customers in the store. So I drove up there to wait at their opening time. A gal came right out, I told her what I wanted, and she said she'd check to see if they had it. So I sat back to wait.
And here's the moment this story is about: As I saw her come to the door of the store with a bag of the food in her arms, I found my eyes tearing up with the relief of it! I hadn't realized how worried I was up until then. But now I should be good for at least a couple of months.
Also went and got a spare bag of bird food for my little feathered buddy. So now I think I'm about as set as I can be for the critters without giving in to hoarding. It's definitely a relief!
