You can buy multipaks of TQs on Amazon for as little as $4-5 ea.

On the other hand since I've never had to use one I was looking at cheaper alternatives one being disposable TQs. Disposable TQs are basically elastic bands that you tie off a limb with. In multi packs you can buy them for as little as $.30/ea
Buying them in packs of 25 or 50 would allow you to have at least a couple in all your FAKs. Since I have 7 or 8 vehicles (truck, SUV, tractor, ATV, UTV, 3 minibikes not counting bicyles and a riding lawmower, a couple workshops and a bunch more FAKs in packs and go bags it might be a good idea to buy a bunch of them.
This is what I found...

I realize these are what they use for blood testing etc but why not for injuries? Does the same thing as a "real" tourniquet.
What do you think? Disposable TQs or regular ones?
