Open a CommSec Account and Get $200
However I missed this "<b>Get $50 When You Open an ING Direct Savings Account (1 Deposit Needed)</b>"(http://www.ozbargain.com.au/node/82829). Only because I opened the savings account together with the transaction account two days before the promotion started. Phoned ING direct and failed.
Forgot to mention the ongoing 5% cashback from ING Direct till June 30,
and bits and pieces from AmEx network.
