Are you just wanting a couple of weeks of food and water, or what?
Is this stuff that you don’t anticipate ever using and just want to put away for 30 years ‘just in case’?
I have enough toiletries and medical items to last me, and I've started building up food supplies. I need to invest in off grid cooking items like a butane/propane stove, a cooking stove that I can burn wood in, and electronic items like rechargeable batteries, an emergency radio and flashlights, but I got a line on those types of items.
What I'm looking for, in the way food items, is a place to order items that resembles a food store, but with items that will last longer than the 2-3 month shelf life of most items in your local grocery store. I don't want to purchase a huge bucket of items, most of which I will probably never use. I want to hand pick what I get, and how much.
