A super quick web search turned up a seemingly-relevant page on MacInTouch Reader Reports, presumably the same page that BobStern mentioned earlier in this thread.
Seems it's for real... in which case... wow. Either that or quite a number of folks are all horribly, horribly confused/misinformed, which seems unlikely, to be honest. The thread suggests you do have to be particularly clear (and maybe a little persistent) about what you're asking for, and it seems to be geographically limited to at least the U.S. and Australia.
If anyone does find a part number for it, it'd be great to share that info here, since that could make it much easier for others to order the same thing.
