I have one of those plastic drawer organizing things you an buy at office supply stores in my closet and it contines backups for all my kits. For example when I buy new bandaids to restock all the kits I buy a nice big box and restoce everything and then put the box in those drawers. As I use things they get replaced from that supply and when that supply gets low I restock it. Basically like the office supply cabinets at work, there may eb several boxes of pens and stapels and such there and people take what they need to their desks. So if I use or loose anything I have resupplies sitting waiting.
