If I am not mistaken outlet inventory is updates many many times a day. They seem to update instantaneously as they get a machine ready it goes up for sale. So keep checking the site as often as you can.
However I think you are a lil late to the party, had you been around a 3 or 4 weeks back they had insane deals on M90.
I got my M90 for $1588 (including tax and shipping).
Hope you get a good deal.
