Comes with the Impact driver, 2x 2Ah 18V Batteries, One Charger and the TSTAK Case to store the Impact.
The Impact driver (DCF840) alone looks to be $149 at the Tool Shed and $200 @ Mitre 10.
It is showing out of stock at a lot of Bunnings locations, but delivery is available so you should be able to get it, just enter your location and it'll give the cost estimate, for me it's $7 in Auckland.
If you get an error in the cart you have to change your Bunnings store on the website to one that has the item in stock, the item will ship from your selected Bunnings store (see comments).
I have one ,It's not a great impact driver it lacks the three speeds of the 887 and quite a bit down on Torque despite what the specs say. It struggles with 100 mm batten screws but good enough for chipboard screws. It's a good setup for assembling flat packs and cabinetry work.
