Followed this link from Insty for a survival first-aid kit, but on scrutinizing the contents thereof, my conclusion is that I’d be paying $70 just for a bag — because I already have all the other stuff, and more so withal.
That said: none of it is in one place, but scattered around the house; so Job #1 is to round it all up and put it into a bag, and I’m sure I have a spare one of those lying around somewhere, too.
