Remember when I wrote about wheat in Why You Should Store Wheat for Survival?  For heaven’s sake, do not purchase wheat if you do not know how to use it.  Of course, it would not hurt to learn about wheat.  Freshly ground, it makes a heavenly loaf of bread the only problem being that it is so good you may eat too much and gain 50 pounds which would be another problem entirely.
Your list may be completely different from mine, but I believe the items contained in this list of supplies will be common to most people and more importantly will be required if you are going to be as prepared as possible if the manure hits the hydro-electric powered oscillating air current distribution device.  This list is not all-encompassing either. I am probably not going to have blacksmith supplies or leather working tools although I can see the use in each of those. This list is going to be for the average person to get by if we have a SHTF event, not start a new life in the wild west. Please let me know what additional items you would recommend and I’ll keep this list updated so you can print it out whenever you need to purchase items or want to build your supplies out.
