How do I buy a game that no one will sell me?

Having argued with several 3rd rate captains of various retail ships over the existence of Guitar Hero World Tour on the PC - I am at a loss. First there was a GH4 SLI profile contained within the 186 revision nVidia drivers, and the peanut gallery shouted Nay! Next there was several announcements from GDC 2009 and still the unwashed, food court-dwelling counter-jockeys of Dorktardia waived my statements from behind their stained and worn copies of GameInformer. Now a Crack and Pirate Release is available and still I am neither able to purloin a copy legally, nor find a single local retailer willing to admit it's existence. What's a recovering Pirate to do?
