Not quite a super deal since you need to have the GEM Visa credit card ($99 annual fee), but they are offering $150 credit back on purchases $1200 or more on the following stores from the 3rd to the 6th of June: JB Hi-fi, The Good Guys, Amart Furniture, Michael Hill, Samsung, Freedom, BBQ Galore, Snooze.
Its a interesting card since it allows 6 months interest free payments on any purchases above $250 and have some extra months for certain stores (24 months @ Apple store, 50 months @ Freedom for example).
Is this only for new customers or applies to existing customers too?
