The old JB gift Card if you sign up with a JB Hi-Fi Mobile plan (powered by Telstra).
It's actually the $99/300GB/ Month deal, but they're giving you $10 off for the 2 years.
$2136 cost over 24 months.
So if you actually need the gift card, it's effectively $1136 for the plan over 24 months. That's $47.33/ month.
(And here i am, about to have my monthly Telstra bill go up from $59 to $65/ Month with 60GB. Not that i need more, I don't use it.
I've just done the maths
24*$65 = $1560
Although I'm already with Telstra so don't qualify, i could spend an $576 extra over 2 years for $1000 GC. I.e. $424 bonus).
