I am an existing Coles Mobile user. I had already set myself to Autorenew on 23 November for a 25% discount, however I just received an SMS from Coles to say as part of Black Friday / Cyber I can get a 50% discount if I recharge.
I've just done that now and got my $150 365 day plan renewed for $75.
Coles Mobile uses the Optus Network.
not on coles myself but this is the first phone deal for long expiry deals i've seen where it's a benefit to existing customers lol
