Great price for a 3M 8K HDMI cable, but it's an INSANE price for a HDMI 2.1 certified one, which this is! Selling online elsewhere for $55-60 for identical item.
As reference, this previously popular deal posted for same cable type, $14 for 1.5m, 3m for $24 in the comments of this thread

If you don't have access to TGG Commerical, gain access by joining Rest Super for free and have no balance (EDIT: comments below suggest there are fees even if you have zero balance @$78 per year. This hasn't been the case for me. Can others confirm? Elsewhere on OzBargain, I have seen someone suggest closing your account but never logging out and perks remain, so YMMV)

If you can't be bothered joining Rest Super, the cable is available through regular TGG for $15 which is still ridiculous cheap for certified 3M

TGG page doesn't say certified, but the Crest website shows certified when you scroll down to the bottom specs. Same product code
