Not much fine print. They're releasing a new line of mics and are getting them out there. If you buy a microphone at regular price from them, you get one of their new M series vocal mics for AUS$1.
The M1 and M2 are dynamic mics and not useful for most film/video applications. The M3 is almost a carbon copy of the AKG C-1000S which I use when I do Foley and sound effects work, but almost never use for production sound work.
