Get the survival and prepping gear before you need it. When you find yourself in a situation and find your in need of a particular piece of gear you had better have it. At that point wishing you had added it to your gear bag does you little good. 
That old saying, "Better to have it and not need it, than to need it and not have it" is more true in a survival situation than at any other time. Even the smallest and simplest piece of equipment can keep a small problem from becoming a huge problem at a later time. The Self Reliance Store.
