>>9452290If you're in burgerland then chances are it's too late. But you can still give it a try.
First of all you need food and water, a lot of it. Food of course has to be dry food, canned food, generally food that you can store away for extended periods of time without it going bad, preferably several years.
If you have the access, buy a gas mask, keep it clean.
Balkanfags swear on addicting commodities that are good to store for shtf times. If you have old world currency to spare and the shops are still open, buy cigarrettes, lots of them. Or alcohol if you can store it. Don't smoke and drink any of it, just make sure you have it, it will come in handy when dollars lose their value and people go back to trading goods.
If you have a little garden, or some pots on a porch or something, learn to use them to grow crops, no matter how little area of it you have. You will be happy for every bit of food you're able to grow yourself.
Since you're a burger, get a gun, preferably multiple guns and ammunition. Guns are a massive advantage in shtf times. If you failed to do so before dollars lost value and gun stores closed, put getting a gun on top of your priority list. Guns are valuable and give you a lot of advantage in a high risk scenario.
