More people need to think about their emergency preparedness. We're not talking about permanent societal collapse; just a week-long collapse of electricity, food supply, water, transportation, or other critical goods.
If you live in a cold climate: go buy an indoor safe propane heater right now, with a supply of propane. Its not that expensive (maybe $100) for the value you will get out of it in the coming years. It can single-handedly be the difference between being able to hunker down in your home, and having to rely on external support that you'll pray is there for you when the time comes. A carbon monoxide detector is also good to pair with it, to be safe. Blankets as well.
Water is easy, though pretty large volume. Food also isn't as hard as it used to be; having a weeks supply of emergency rations is fine, but consider: Soylent, Huel, etc. Their powder form has a published shelf life of a year, its volumetrically dense, nutritionally complete, only requires water to make, and tastes pretty good.
CASH. Some way to start fire. Candles. A couple flashlights. Batteries (the huge ones made for camping are fantastic, though expensive). Two way radios with very long-range are also a fantastic investment; imagine its the winter, power & cell service is down, and a loved one has to try a local store for some supply you forgot.
