Yeah New Egg has had it on 2 seperate occasions for $28 but they can't keep in stock at that price so here's one that's more stable at $30. Also you could PM this at Best Buy or maybe Walmart if they still have the game, or if you're needing something to spend GS credit on. For those that don't know, you get both WKC games on the disc.
