I bought a 12+1 Xbox live code from Kurhn_de tonight. I got the code in about 15 minutes, went on the website, entered the code, and I'm set until 8/2010. Excellent deal.
I really don't think LSC is shutting down, moving to SearchPearks, or any other area that MS owns. I believe that a lot of people are cashing out due to the holiday season and they'll restock the prizes within the next 2-3 months. Let's hope, because I really need Rock Band! :D
