Where are you at? Common for snowy winters? I'm in PA where growing up we constantly had snow, 6-8-12 inch storms. Common to wake up as a kid with 6 inches of snow 2-3 times a week and still heading off to school.
Our winters has been mild for years lately. They sensationalize it on the news warning of our impending death with a 2 inch storm once a month lately.
Even back then, they would empty the shelves of milk and bread. Worked grocery back then in high school.
Walmart wasn't around back then and we had 4 different grocery chains with multiple locations and they would be packed before snow was coming.
Now, we have Walmart and only 1 actual grocery store (2 locations) that is ~30-50% more expensive than Wallyworld. I can't afford the grocery store so I go to Walmart, but I can't tell if the shelves are empty as normal or because of our horrendous 2 inch storm coming. I don't know what's going on, I barely eat anything because I don't have food available as Walmart shelves are completely empty every time I go there. Before a snow storm, may as well just forget about buying food.
