C&C is only available at their VIC store or $11.99 nationwide delivery otherwise. First time this card went under $300? Lowest posted before was $284.10 delivered. Next cheapest is $351.20 delivered using eBay's current 20% off coupon.
You can also take part in AMD's "Raise the Game" promotion, even though they are not listed as a participating reseller. I contacted their customer service, and they said a code will be included inside the box regardless. There's also about 40 units left, according to cs.
In terms of performance, I believe it's equivalent to and in some cases better than a 1060 6GB, great for 1080p and even 1440p gaming.
UPDATE 11/11 12:00am: Back in Stock
Great Deal. Have been looking around for an Rx 580 8GB, and this one is definitely one of the better ones out there for this card.
Thanks OP!
