This looks to be a promotional item and in very limited stores, The bargain in this deal is that it includes the new sealed 3.0AH battery which is $79.98 on its own.
If like me, you don't need the charger, just sell it off straight away. I have no trouble selling them off quickly for $10 on FB marketplace.
Unfortunately available so far in a very limited number of stores in NSW, VIC and ACT only. Hopefully they have more stock and roll them out to other stores soon, so may be worth checking back on nrby later on.

From comments below, it looks like Bunnings site is doing its weird thing. The direct link above works for me in Canberra so It might also be location specific. I can also get it to show on this search, https://www.bunnings.com.au/search/products?q=ozito+pxc&sort…
