While purchasing the Dewalt multi-tool listed on special earlier on the forums, i noticed a Dewalt angle grinder on special. It was out of stock at my store, but looking online reveals there is stock still around.
You might also be able to price match the item with this website - https://alliancehardware.com.au/dewalt-dcg406n-xj-18v-xr-li-… for a further 10%. I have not personally tried or seen anyone with evidence who has, but it could be worth a try.
It is also worth note that you can special order the DeWALT 18V 125mm XR Brushless Slide Angle Grinder without the paddle switch for $249 on bunnings online https://www.bunnings.com.au/dewalt-18v-125mm-xr-brushless-sl… . I don't know the inital price of this model, but the only difference between the two is the paddle switch so i would presume they are around the same value.
This was $249 for ages about 12 months ago in a kit that come with a 5Ah battery and charger. I would wait if not desperate
