I got halo wars , fable 2 and gears 2 goty minutes before the price went up. That deal must have been valid for a certain amount of copies for each title.
On the thread on RFD some guy said he managed to order 4 copies of Gears 2 at that price.
So if you are wondering why the deal went dead so fast, the answer is "RFD Hoarders".
I also bought an Elite (120GB + Lego Batman + Pure), it was 250 $, which was probably the lowest price I would have found during boxing day. I think that deal is still up as we speak.
The only bad thing is that I couldn't make the "free with an Elite" Ghostbusters (360)
Now I need to input the referrer deal to get that free On Demand game and 1600 ms points
