Ten days later, and they still haven't shipped.
I thought I was ordering a $2 post card and apparently it was $2 in another world, not australian.
However, the link that brought me to this joke of a website said that they were working with the Australian Post Office.
They charged me $5plus chump change for 1 post card. I went along with it because I wanted the thing done. I did it for 2 cards.
I do not know the status of these post cards that cost me more than double what I intended to spend.
