My local Best Buy has it on clearance for $20 along with Zombi U, Assassin's Creed III and IV, and Batman Arkham Origins.
Should I bite on any of these? Mind you I have a back log though and am kinda tired of 2D platformers (still haven't beat either NSMBU or DKC).
As an aside I get the feeling Best Buy is clearing out a lot of their Wii U software section (the third party portion of it anyway), I guess that's where all the Amiibo toys will go come November.
