I had one for sale for awhile for $80. Couldn't sell it so I sent it away with a bunch of other stuff to BBTS.
It was a giftset of Cybertron Optimus Prime and Wing Saber with a DVD (Canadian Version didn't have the DVD) and was only available through Costco, which requires a membership to shop at their store.
Sorry when I read your post I transposed two words (it and is), which turned it into a question in my mind.
Well, that's an interesting point you make. Doing a quick look on eBay, I found at least three MISB Cybertron Prime's (both the original and GF red & black redeco) going for anywhere from $80 to $130 and two MISB Cybertron Wing Saber's going for $45 to $80. So... actually it could cost more to get them seperatly. Of course, if you wait around and don't get bid crazy you can probably find them for cheaper (I know I recently, like last month, got a Wing Saber that was MIB for $35).
