It might show up at other "fan specialty" stores, but JBHifi looks to be the first one to get Legacy Deluxe Red Cog (redeco Siege Cog with some extra weapons), which was a Target exclusive in America.
The price is $45, which is above their $40 Deluxe price, but less than their Voyager $55... which is actually a good thing, as Red Cog was given a Voyager class price in America at Target and Hasbro Pulse.

The listing was just put up on the JBHifi website today (along with a number of other new items for them, including some old items)... so that you can see if/when it appears in a store near you, or to order it.

People here and on our facebook page have just sighted it in-stores in the last two days in Victoria and the ACT, so itshould be showing up in other stores soon too.
