Don't think it's been this cheap since launch, mostly posting so someone can tell me why it's terrible purchase.
Requires afterpay and using both codes.
Was also recently ~$816 via amazon with included discount: https://au.camelcamelcamel.com/product/B0DKFMSMYK
Also ~$70 cheaper for OEM version on AliExpress but local/amazon warranty probably worth the difference: https://www.ozbargain.com.au/node/907064

It's a terrible purchase! /s
Jokes aside, it's not great value to be fair. But if you want the best gaming chip, it's the only option! I reckon a ~600 dollar 7800X3D is probably the better buy though, given performance difference in most games is 5-10% at most.
Even more still if you wanted to be more budget but still make the jump to AM5, the Ryzen 7700 Ali Express deals can't really be beaten!
Edit: Metrocom eBay have the 7800X3D with APEF10 Code 10% off for $629.10.
