Amazon has Assassin's Creed IV: Black Flag Skull Edition for PS3 retailing at $92.50 inclusive of shipping. This is a pre-order item that will be released on November 1 2013.
I compared it to a number of other online offers and this seems to be the best deal right now. It is $101.50 shipped at JB Hi-Fi, $106.10 shipped at EB Games and $103.95 shipped at Harvey Norman.
