I really can't work it out. Some sellers charge around the $4 - $7 range, which I think is quite reasonable. Others are around the $10 - $12 mark, maybe OK for a high end card. Then I've seen some up between $24 - $33 for a single card. Now who is going to buy any card that will end up costing $30 more and likely just as long to arrive? They might as well just say that they don't ship to Australia.
