From what I understand, this was never actually packed as a "combo". If the pieces come in the factory boxes, it should come with the mouse pad.
I ordered one while sitting in traffic on my way to work this morning. I almost ordered just the mouse for $40 the other day. This should go nicely with my new rig.
As for 1SAD, I'm pretty sure it's a small operation. I've always gotten my orders within 2 weeks, but I would assume it's due to fulfilling orders between them and their other affiliate sites.
But if you're scouring deal a day sites for something you NEED IMMEDIATELY, you've already messed up.
I placed my order on 16th, Order status still says "Processing". Hence the month-long-wait myth corroborated(well almost)
