Another long time lurker, first time poster emerges from their laziness.
I've been having an eye on a Nikon Z6 for a while on Amazon and Ted stores. Amazon has been selling it for $2,488.95 for a while. With the $500 cashback it now comes down to only 1,948.95. I believe it might be the cheapest so far. The deal could even be sweeter if you are traveling oversea (like I am) and claim GST refund.
All thanks and credit to DSOTM for his cashback post: https://www.ozbargain.com.au/node/451762
Edit: I reckon it is worth to mention the current 12% cashback at Shopback caps at $50 bucks. Thus, using cashrewards (5% for electronics) would be much better.
