First off, yes this is a bad site. You need to create a free account to see the prices.
As it's limited availability I'm not sure if every state can access this deal, as a general rule with blackwoods if it says delivery will take 21+days then it's probably out of stock for you but won't tell you until you actually go to pay (like I said terrible site).
Having said that this is a good deal for anyone already in the Dewalt eco system
The skin alone sells for $529 at Sydney Tools and Total tools and the battery retails for $179
