This is the only active discount available (at least that I know of) on the Switch OLED Model (not counting EB Games trade-in deals).
Not here to debate whether or not this is worth it. But if you are after the Switch OLED Model, this is a good price compared to everywhere else.
RRP is $539, so that's a $36.05 discount.
Releases Friday October 8th - couldn't tell you when you'll actually receive it, though.
EDIT: I've been made aware that it was 25% off (down to $439) at one point on Kogan with Klarna. So this isn't the best it's been, sorry everyone!
EDIT 2: Despite the code saying it expired on 30/09/2021, it's still valid today on 01/10/2021. So have at it. No idea when this code actually expires.
EDIT 3 Code has updated. Now valid through to October 14th.
Could've gotten it for 25% off if you paid with Klarna: https://www.ozbargain.com.au/node/643872
