I added some to my post also, you may want to reread it.

If you want one... About the cheapest way to get them is through the NRA, as part of the NRA Survival Tool Kit...
It is cheaper than most places sell the Blastmatch by itself!
"The kit includes the Jet Scream Whistle, Star Flash Mirror, Blast Match Fire Starter and Wet Fire Tinder cubes."
All for $15.95!!!!
And sometimes they are on sell for less than $10.00!!!
The case it comes in is worth that!
