I'm just paying with a credit card. As you say it just shows up as Coles and looks like a transaction where you only buy groceries.
There is a possibility of paying with a e-gift card purchased at ~96c on the dollar. There are many different experiences with these - but my experience is that you need an e-giftcard with a remaining balance of at least the cost of the giftcard (incl. activitaion fees) and you need to do it through a self-service checkout. It's also a pain because each giftcard needs to be authorised by the attendant.
In the past paying with e-gift cards was easier as there were many ways to buy discounted e-gift cards of large denominations at ~96c on the dollar. But now you can mostly only get $20 or $50 denominations (which is obviously no good if you are looking to buy a $100 or $250 card).
