The deal posted here is actually for a 12V Brushless Drill Driver Kit, not a Hammer Drill Kit. Edit: The Bunnings website and the deal have now both been fixed.
The 18V hammer drill kit is $149, which is still a good deal though, imho.
Posting this as a new deal so we do not get confused and can make an informed decision. Cheers.
Note: There is no mention on the Bunnings' product page that this is a kit. (Though the picture does show a battery and charger.) However, it is definitely a kit that includes a 2Ah battery and charger, as seen in this photo of the actual product.
No, that deal is for a hammer drill, battery, and charger. It is cheaper than this because it's the 12V series. The one you posted is the 18V model.
