How do you use your cc to buy those mate? If I go to the local lotto kiosk to buy our weekly lotto, I am charged interest srtaight away on that money as its considered gambling. So I use the lotto kiosk at the news agent and I dont get interest charged as the bank does not know whether I purchased lotto, scratchies or a newspaper.

But seriously I would be keen to find how this is done if you are willing to share.

cheers
