The ones I see on the internet for $300 are for the container only, they are not loaded out with supplies.
One can put together a kit, but one needs to know wth they are doing in that regard. For instance what kind of suturing materials, what kind of necessary supplies can one obtain without a prescription, what kind of things can one obtain from nurse and doctor friends, antibiotics, anesthesia, etc.
Often thought I would tell my doctor I was going into the backcountry up in Alaska on a scientific mission for several months and needed some emergency “stuff” to see what he would recommend and perhaps provide (he would know I was BSing him but wouldn’t say anything).
Gotta’ hit the sack, good night!
They usually have them at the gun show near me for about 400 bucks. These aren’t just the shells, these are complete, loaded with all the supplies.
