No that's called price gouging, or profiteering, i.e. taking advantage of people in the current ASIC environment.

Whether you buy now, or later at his reduced price you are likely to profit the same (if at all), as he steals all to gain from the situation for himself. All you've done this past month by owning one is make cash for friedcat. The same of those that buy now in a few weeks time when prices are slashed again. It's nonsense to buy anything from asicminer unless for novelty purposes.
