I saw the 6 coin set in my local Post Office shop today, they didn't have the 2 coin set and when I asked they said no, none in stock, may not get any.
Yes, the big set looked great, but I think it's a bit of a con that you have to buy both sets and still only get 2 "special" coins.
Note there is presently a reduced price, $95 inc GST for the 6 coin set ....
"The 2009 Six Coin Proof Set was incorrectly advertised at $115.00 both in the Mint Issue, order form and on the website, the correct price is $95.00, with an increase to $115.00 to take effect from the 31/12/08. The Royal Australian Mint apologises for any inconvenience this may have caused."
