Hey
I live in Europe, Estonia. I have small apartment with wife and 2 kids. I'm in no way a prepper.
I followed advice in book Cody Lundin: "When All Hell Breaks Loose...". For any disaster he advices to take care of things in this order: Mental preparedness > Shelter (includes clothing) > Water > Food > Sanitation > Lighting > Safety
I have nothing to add to mental preparedness. I had open talk with wife and parents, where to go, what to do, what to expect. We made lists of things we use daily. Everybody agreed that the bright side is that this virus does not touch small kids.
For shelter i have backup apartment with wood oven heating. I think it has like half year supply of firewood. The book advices against going to the woods and trying to Rambo it out. I have no place to go outside of main cities. So thats where i'll be.
For water i got water canisters for 2 weeks supply, or 110 liters. And water treatment chemicals if mains supply is disrupted. I had buy iodine, because chlorine bleach is banned for general public in Europe. That was a big shock for me, I understand that you guys in America can buy it in supermarkets with no problem.
For food i got 1 month of supply of things we usually eat, and that needs preparing with hot water. Wheat, spaghetti, canned meat, various canned vegetables etc. We use same stuff to cook daily meals, except canned meat. I also got about 1 week or less food that does not need preparing, like cookies, peanuts, candy. I bought gas primus and another heat source, swedish army ethanol burner (don't know it's english translation) for cooking. Coffee and wine for comfort. I'd advice you to stock up anything that you use daily, like smokes, or anything that you have dependency on, mine is coffee.
For sanitation. Trashbags for toilet, lots of soap. Masks are all sold out in local stores, i ordered some from amazon.
For lighting. Led lamps, flashlight, batteries and candles.
For safety, nothing. I don't know if it's wise to get a gun. Based on the book, violence is not the main reason for death in disaster, its pretty much the last.
All that cost me ca. 700 euros, or ca. 800 dollars. Things that cost the most were medical supplies, gas primus, N95 masks that i ordered from amazon for probably triple price, water containers. Food was ca. 200 euros.
I also know from personal experience that water treatment and power generation atleast in my country should not get distrupted. Entire process is very automated, and i have worked in automation in both areas.
I was laid off also, a week ago, thanks to coronavirus, business dried out and management paniced. Theoretically, i have 6 months, or 12 (thanks to some unemployment insurance) if I put some effort to it before i have to go touch my investments. I was laid off in previous crisis also, in year 2008 or 2009. I had cash reserves then. So i just did nothing, worked on hobbies, worked out, it was a nice relaxing period.
