It's a little bit complicated but here is how it works. Use eligible commbank card to get the commbank cashback rewards. Get $30 cashback when you spend $100 or more at Kogan. Active the rewards from the commbank app and then buy the sodastream with commbank card + kogan first membership for free shipping. I think you can try its membership for free. That will take the cost of buying this sodastream to $79 $89.
Here is the commbank rewards offer I got from the email
