Cheap Source Of Propane?

When I got a new can of propane, for my torch, it was $9. At wally world, it was $4. Then, when I went to get a can of cooking stove propane from the camping department (at wal-mart), I notice that the tank was $3. After getting home, I noticed that the threads were exactly the same, and that the torch head would screw onto the neck of the "camp propane" bottle. So, as anyone would do, I fired it up, and it worked! Of course, it would shut off it you tilted it too far, but what the heck! $3 for a can of propane. But then I thought "Why is this so cheap, and why haven't I heard of this before? Is ther something wrong with this? Will I blow myself up?!?!?! Anyway, I'm all for saving $2, or $6 (depending on where I go), so is this actually a reasonable way of saving money?

So what I'm asking:
-Is this way safe? I haven't fired it up since, in case it did something bad.
-Why is it so cheap to but it that way, and so expensive to buy regular tanks?
-Has anyone else done this?

If anyone can help, it'd be appreciated.

Well it should be safe if the threads match up fine, but I would use some pipe tape to be sure. The reason they are so cheap is A.) There's not really that much propane in one of those little cans compared to a BBQ propane tank. B.) The tanks for a camping stove are a bit cheaper because the tanks are thinner than those for torches because the manufacturer assumes that it will be sitting stationary. Not standing upside down and welding with it where ya may drop it. (NOTE) Another chance would be safe to say that they might have been dropped in the back room and "quietly" brought up to the shelf.
Absolutely DO NOT use "pipe tape" on the threads. The threads have NOTHING to do with the seal/preventing a leak, they are only there to hold the nipple on your torch head secure, centered and into the nylon seal bushing in the propane tank.

And, to answer your question, yes, it will work fine. Provides a nice stable base for soldering, etc., compared to the skinny torch tanks. Used them for years and never had a problem.

Okay, thanks, that is what I guessed.
I haven't had a problem with it. And, the camping tanks are 16 oz instead of 12 oz (last I checked...). Short, squat tanks would work better (be more stable) in a camping setting where long thin tanks might fit better in tight spaces of home repair. You might skip the camping fuel if it's more expensive, but if you need it for home repair, you don't have a choice.

Okay, so you are saying youve done it without problems (not to say nothing could happen)? Good.

Thanks for asking the question John!!! I just got the coleman tank too, but then hesitated to hook it up for fear I'd blow us up. Good to know it works fine.

If, by torch, you mean one of those type that is often used to scorch and remove paint, or solder copper pipe, I personally didn't even know they made "special tanks" for that. The little tank I use for my hibachi I also use for a light duty torch.
