There in the classifieds all the time, so that's your best bet for a speady aquisition, otherwise you need to get on the "Notify Me" list, combined with keeping tabs on the GG and COV forums for updates to when the next preorder will be. I think they only went on sale twice last year, it's a minor job just to keep track of what's going on really. The Classifieds though, is the best answer to your specific question.
