I think you'd be surprised how much you can get for $200, especially if he has some items already. Just keep in mind that a household first aid kit may be different than one designed for worse injuries which you have to treat on your own. I would be careful about trying to shop for one-stop survival kits rather than picking and choosing supplies and making your own, because after a certain threshold, those kit makers are throwing in a bunch of things of questionable utility to try and justify the cost, rather than streamlining it for efficiency and catering it to you.
If I was going to spend $200 on a guy's bug-out kit, here is what I'd shoot for.
-- Stuff you already have- he should keep a couple of pairs of socks and underwear in there, and he should be ready to throw in any needed prescription medication he uses before you run. There should also be a couple of small items which are significant to you- things like photos of your loved ones in a zip lock bag, a meaningful piece of jewelry, a favorite toy if it's for a child, etc. And of course existing medications and first aid items you just had on hand, and any shelf-stable food you have in the house. You could also print out google maps, or any instructions you felt you wanted access to when the internet goes down.
-- $36 after coupon- Even on a budget you want a good backpack because the
-- $42 -This is a good place to start from. It is pre-made, but at $42, it's a good value for what you're getting- case, shovel, hammer/axe multi-tool, knife. a mess utensil, a lantern, A compass and a paracord bracelet, fire-starting supplies, fishing supplies, more first aid supplies, emergency tent and blanket, rain poncho, cord, flashlight, card tool, wire saw and other common survival items.
-- $30- This solar/hand-crank flashlight which also acts as an emergency weather radio and batter bank to charge your electronic devices.
-- $12- Add this suture pack to your first aid kit to help you deal with larger wounds.
-- $17- this is a nice little mess kit, with a good compromise between being compact and having enough components.
--- $32- you obviously wand some kind of primary weapon which hopefully has other applications. This machete would be a nice budget pick.
-- $11- Normally I'd list a number of household medications as needed, but we're tight on budget, so this multi-pack with a couple of doses of the different essential OTC items.
-- $14- This pack of three water filter straws will help greatly.
-- The remaining six items are a dollar a piece at the dollar store, and will round out a solid budget kit - a Travel sewing kit, A hand towel, a travel toothbrush kit which has toothpaste/brush/brushes, a 2-pack of bar soap , lighter and a deck of cards.
A good battery powered radio
