Update: It seems as though Sony has made the items unavailable to purchase as of a couple of hours ago. Post will be updated if it becomes purchasable again.
There was a 'damaged box' sale from Sony which was posted on OzBargain before. The damage was almost completely cosmetic with things like half peeled price stickers and scuffed corners. If this sale is the same, this is an absolute bargain price!
