This is my first submission to OzBargain so I hope I'm doing this right. Just wanted to share this deal for the Razer Viper Ultimate as it's a very popular wireless mouse right now, and I believe this price is the lowest it's ever been in Australia so far.
Computer Alliance have it listed at $219 on eBay, however with code PLATEAU it is discounted to $186.15. Postage is free if you have eBay Plus (you can simply use a 30 day free trial if you don't have Plus). The code is valid until the end of December 2019.
Hope this helps!
