The funny thing is watching what really flies off the shelves locally when we have a big snow storm forecast.
1. Bread
2. Totinos frozen pizza
3. Lean quisines
4. Snow shovels
5. Meats
Nothing with any shelf life, just the stuff they'll need for the next few days so they're not inconvenienced.
I had an on line friend from Serbia and he said their family business became refilling Bic lighters with a propane cylinder. They found a niche need and were really the only game in town, so it was enough to get them through, but his stories of hardship and bitterness was heartbreaking. Suffice to say, he's not a fan of NATO.
