I've been keeping an eye on these tiny camping / hiking stoves for a while and just received this deal via email. The email said it was a 48hr deal only, but who knows.
Normal price is $11.something.
These things weigh a paltry 25gms and fire up really well.
There's heaps of reviews around the various hiking and bushwalking forums mostly praising these units:

The only criticisms i can find relate to the longevity of the aluminium thread. This won't be a problem if it's taken care of, but for this price I just bought two!
There are tons of these on ebay, lots of different variations. I got this one (located in Australia) after searching a bit; it's one of the cheaper and smaller ones but it comes with a piezo lighter so you don't need matches. This looks like the same thing, but a bit longer shipping time. Just search for "Hiking Stove" and you'll find a lot of options.
