Same as this one from earlier this year.
2 months BINGE Standard is available to new and returning BINGE customers who are activating a BINGE account on Optus SubHub for the first time. Available on BINGE Standard only. Not available with any other BINGE offer. Must sign up via Optus SubHub to redeem, not available via third party billing platforms. One redemption per eligible Optus SubHub account holder. Offer ends 27 November 2023 (extended from 12 November).
I'm sensing the amount of existing Optus customers who are still with optus this week would be slightly different to 2 weeks ago
