One thing you may to want to keep on hand in your preps is the lint from your when you do laundry. It makes good kindling to start fires in your wood stove and for starting a fire for your campfires and cooking fires. Good thing about it wont cost you anything, because you get some of it every time you dry a load of laundry. One thing you should make sure of is to clean the filter in your dryer after each use. A good friend of my family caught on fire about 9 or 10 years ago when her dryer caught the lint on the filter on fire.
