EDIT: Based on people below, it seems like this is very much a targeted offer. Strange, given it appeared on the home page for me. Sorry if I wasted anyone's time. Still worth checking your emails if you ask me.
A bit of a niche deal, but a great deal if you are eligible.
Telstra currently have a promotion in which you can recontract and get:
- ETF waiver;
- $200 credit on your bill; and
- 2GB bonus data per month.
The kicker is that BYO plans are eligible for the promotion. In my case, I got my $200 ETF waived and $200 credit for the $50/m M plan (7GB a month with the above bonus). That means the next 12 months will effectively cost me $200 for 7GB of data a month. You should see a screenshot here: http://imgur.com/a/lH8tu
It's pretty rare that Telstra has a plan that makes it on Ozbargain, but I think this gets over the line.
The one thing I'm unsure about is what you need to be eligible. It may be <3 months remaining on your contract. I couldn't find any fine print to tell me, go the website to check.
Where are you seeing the $200 credit on the website?
