IMO, and I am by no means an expert prepper, but canned soup seems the smartest purchase to me. Dried goods might have a longer shelf life, but it isn't food so much as access to clean water - and lots of it - that will be crucial to any survival scenario. Beans and Rice both need a fair amount of H2O to be prepared, and every ounce is water that could be otherwise utilized.

Plus, soup comes with it's own water.

I did purchase a 4-pack of Lifestraws recently, as well as water purification tablets (cheap) and de-iodinization tabs (cheap and make the purified tab water more palatable).

Otherwise, my water plans rely on rainwater and various catch basins (including a swimming pool XD).

Feel free to pick any and all of this apart. I am at best, a novice regarding these things.
