The surplus store here I use, keeps the 1K spools right in the middle of the floor. They want that stuff gone.
I do the same thing, but my favorite thing is the "browse" feature of the surplus store. I wander around for an hour just reading stuff on the uniforms. Pretty cool.
Para-cord dot com is another good place to find what you are looking for, as well as Cheaperthandirt. They have the new 8 strand for sale now, or at least they did in the new Master catalog
