Such kits usually are overpriced, I found. Do your own collection.
For the worst, and as a last line of defence if other food of ypours has run out: NRG-5.
Crates with bottled water. As many as you can store. Of water you never can have enough.
Diversify you options to run a fire for cooking, as long as you dare cooking (safety from crime). One can imagine situations when one doesnot want to attract attention from lighting a fire. Gas cartridges, fuel, gasoline, wood, coal, if you have options to use any fuel you may stumble over, thats not bad.
Oats, rice, hirse: Wastes no water, like boiling potatoes or noddles would. Long storage if stored dry, and cool.
Canned bread. Other cans, as previously described.
Honey, unlimited shelf life.
When things are desperate and the going gets too tough for you: Liqueur. The poor man's cyancali pill.
