I don't get why you keep whining about sellers not responding. You even said that if you did not find a used copy by January 11th, you would buy a brand new one, and here you are still bickering about sellers and looking for your first used copy LOL. Seriously, why don't you just go and buy a new copy from XenForo.com like you said in your previous thread:

I don't think anyone would want to deal with you when you got that attitude.
