Stratagos, I stopped at the supermarket before the last storm, not to get 'staples', but to get Red Potatoes. (Needed it for a recipe). I heard someone ask why people stop to get bread and milk before a storm, and I heard a woman (in line in front of me with bread and milk) 'you need it for school lunches'. Now, school had already been cancelled for the following day.
Your kids will survive for 2 days without milk. If you have a chance, yes, by all means get it, but why there is a rush I never understood. There was a rush on Tuesday night. So that means, in absence of the snow, all these people would be going on Wednesday or Thursday ordinarily to get milk??
