I still dont get how that its relevant to the discussion of this thread which is so clearly about tefillin?
Context.
I wrote it in response to:
But they won't do the same when a Chabadsker has tefillin on offer.
Is it because they are more embarrassed about tefillin than about lulav, or because they wouldn't trust the kashrus of chabadsker tefillin? 
And I made an allusion to the fact that there's a heightened awareness to Kashrus of tefillin in Lubavitch, which I don't think exists elsewhere.
A possible outcome of that awareness is that IINM prices paid for tefillin and mezuzos are generally higher in Lubavitch circles.
