$200 cashback with any $30+ Telstra mobile plan at Harvey Norman
I am pretty sure you need to sign up for a 24 month contract but you then get quite a good choice of mobiles free.
I can't find any details at the Telstra site - so I might need to head back to HN.
But if anyone has info please share.
SO a minimum spend of $720 for 2 years and you get a free phone plus $200 in your pocket.
