This is for the actual surviving part, not just buying the right shit:

>How to eat food once electricity/gas runs out. Candles?
>How to dispose of trash when infrastructure has fallen
>How to clean dishes without water
>How to piss/shit once plumbing doesnt work

Add anything to survive atleast a month or two, hopefully until military has gained control and the governments readjusted and most importantly, food and water are available again.
