I really want to get Starcraft 2 !!!

Starcraft 2 has been out for almost a week now, and I still have not bought it. I have just been too busy. My fiancee is moving in with me and i have been trying to get my house cleaned up and comfortable for her. I have even been to Target and seen Starcraft 2 on the shelf just today! But i cant get it there. I want to go buy it at Gamestop so I can trade in some of my xbox games. The most valulable game i will trade in is Halo 3. I am not sure how much i can get for it though. Once i get starcraft 2, i know that i will end up playing it for hours. It will be hard to make time to play it. I will probably sleep a lot less so i can play starcraft 2. I will continue to go to the gym though. I got to keep my fitness up. I am tired of being a skinny out of shape weakling.
