Just as a tip for others, I realised as a member of Suncorp Benefits (through my AAMI insurance policy) I can get 6% off EB Games gift cards. They have a daily and weekly limit of $500 EB gift cards purchased through the program so I bought $500 worth yesterday and will hopefully have time to buy two more $500 cards (since I have two Unicrons on pre-order).

Every little saving counts so I suggest if you are a member of this program or others that you check if you can get some sort of gift card discount.
