I was going to use this to buy one of the expensive Turtle Beach 360 headsets, but the X11 ($70) was backordered, and I just noticed they added the $30 Turtle Beach headset that came out recently, so I used a $20 off coupon, and got it for under $11 shipped. The X31 ($100) might have been nice, but I don't plan to use a headset too often, so I'll check out this cheap option. The not yet available X41 ($200) would have been absolute overkill.
25OFF still works, so I preordered Halo:Reach, Fable 3, and NBA 2K11. I had already preordered Reach and Fable using the 25OFF code a few weeks ago, but wanted to make sure I ordered when Reach showed the $20 bonus credit, so I canceled. I guess I'll see if everything works out in the 4-6 months from now those games come out.
I did all of this with credit from the $140 trade in value of the 360 a few weeks ago, and the refund that made The Beatles: Rock Band bundle free, which is also where I got the $20 off coupon. Game Stop has been incredible for me this year.
