The store items are listed in the hotbar categories (top of your screen) are all affiliate links. This helps keep the site ad-free, along with alleviating server costs, and so forth.
ALL of these items are either ones I personally own, or are ones I would, or have recommended to friends and family. If there's something about an item you've found doesn't personally work, feel free to reach out and let me know! These are just what have worked for me, and what recommend based on far too much research, my career, and education.
The menu above allows you to navigate by the pillars of preparedness (Communications, First Aid, Food, Water) and then also by specific scenarios and disasters for hazard-specific items. (Car kits, EMP, etc.)
