Not sure if they're clearing these but figured a discount of $80 off RRP was decent, then got the powerpass discount also.
Model # on box is PXLMK-4182. Only difference I could see from the website listing for the similar PXLMTK-4182 is that it comes with 2x separate chargers and not the 1x charger that charges 2 batteries.
Was hoping to pickup at least one more 4.0a battery (as my yard is a little over 400m2) but they were out of stock at that store.
Edit: As confirmed by a rep, this is the regular price for this model, it's just not listed on bunnings website.
It may be nationwide, just notices same price in another store.
