JB Hifi has the G Pro X Superlight listed for $279. Been eyeing this one for a while, waiting for it to go on discount. Great mouse, one of the lightest on the market, and most aesthetic mouse out there in my opinion. I've owned a handful of gaming mice and this might be might actually be my endgame.
Lowest price it's ever been, I believe.
It helps if you correctly add the product tag to your deal: https://www.ozbargain.com.au/product/logitech-g-pro-x-superl…
Seems there was a deal on the white model for under $170 not long ago, using a similar mechanism.
If you're not fussed about colour, it's regularly below $180 these days, and I'd imagine there'll be some big deals next month.
