I found this stuff just a little while ago, and while it's not necessarily on sale right now, this stuff is a great deal for how many uses you can get out of it.
This is the stuff that parachutes are made of and it will hold up to 550lbs without breaking.
For anyone, like myself, who is always looking for things to add to his trunk in case of emergency/zombies, I was surprised to find that I've never seen this stuff before.
It's enough to do basically anything that requires string/rope, and it's well priced to boot. I bought 100ft of this stuff and loved it so much that I went for a 1200 foot spool which is on it's way to me now.
Anyways, give it try.
