This deal is for accounts who've already lapsed their Binge Free Trial and are not currently subsribed to Binge.
Due to issue with the streamotion payments provider (https://help.kayosports.com.au/s/article/Billing-Partner-Mai...)
They are unable to verify whether you have had a free trial in the past. SO just login and activate subscription
Please note that I would suggest using a prepaid card for this with limited balance just in case. They try to charge you later.
My prediction is that this will give you just short term access to service before they realise and start cancelling the subscription.
Again This seems to be more of a glitch than a deal and proceed at your own risk.
