These Ring cameras are rarely on sale. Most of the time eBay codes don't work for Ring AU eBay store, but this time they do, so it can be had for $30 less.
The wired model is also available for the $289 using the same coupon code.
Edited, so for the battery model, this is not a deal. I myself went to Bunnings and bought it for $199, as per this deal.
Edited, now can be had for $179.1.
