I bought several Quick-clot for my first-aid kit years ago and only recently had a need to use it on a injury with a friend. I got to tell you this stuff is crazy good thing to have.
Rather expensive if you get the full mil spec ones but well worth it. He had a pretty bad cut was bleeding out bad... used this....he's still around and all better.
Lots of bandaids I seem to go through a lot of those with kids and being outdoorsy type of family. E-bay or Amazon good for bulk band-aids 3 X 100per box of 3/4 x 3in for 10 bucks and they are hospital quility.
Little surgical kits come in handy for more then just medical emergencies these are fairly cheap also on Ebay
just some thoughts
