because if the power goes out for 4 to 5 days, you need to have shelf stable food. ppl have kids who may eat two of their meals at school now they're going to be home and expecting to eat 2 to 3 times a day. ppl may not always have a lot of canned goods and shelfstable proteins.
I don’t understand why people start stocking up on stuff for a snow storm. Like just get your regular groceries. You don’t need a month’s worth of shit.
