Did you see the other thread about Haas discounts? I don't know if your question was answered there.
I think it is possible to be fairly confident some discount, or a special package deal on particular machines, will happen around the time of all the major shows.
Incidentally, if you spend a bunch of time looking at the threads in the Haas Mills forum you will see several dealing with the MiniMill. My opinion is that it is underpowered and too slow and the Super MiniMill offers much more bang for your buck.
An open mind is a virtue...so long as all the common sense has not leaked out.
