Looks like other global market issues this week is rattling resources and currency markets, and the AU$ is dropping fast (which is typical, for those going to order BotCon attendee and non-attendee sets).

Since I posted the figure above a week ago, the dollar has dropped half a cent per day, down to US$0.87 today.

That's 6c in the last month, which will add about AU$20 to the cost of the boxset.
