Xbox 360 Live 4000 Points
Apparently this is listed as a game. 1600 Xbox points are 1600 Xbox points. Worked just as expected. Good value. Paid extra for faster shipping, took longer than regular shipping usually takes. Couldn’t post this until I rated it as a game. Since its not a game, I gave it the lowest game rating.
