That just sounds weird, having stock in the back, and lying about not having it, to the point of having to hide it from everyone. Unless they're hoarding stock to try to make sales figures for another period or something...
Yeah, something is going on, it is weird. Someone mentioned in the "In Store Today" thread that they went into an Apple store and were told there were no rMBPs. After talking to the employee for a little bit, the employee confessed they had 1 to sell and sold it to them.
So it appears that they are holding them for some reason.
