Similar to the vinomofo deals, this one is from Crackawines. This "2010 Mystery James Halliday 95 Pointer" looks like the Tyrrell's 2010 Vat 8 Hunter Shiraz Cabernet:

Assuming I'm correct that it's the wine above (the listed price, rating, and drink by date all matches Halliday's review), it's currently on sale for $29.99 (+$6.95 to Sydney). This wine currently sells for $66.49 @ Dan Murphy's:

On top of the sale price you can get a further $50 off if you have an AMEX card and using the coupon code "AMEX", dropping the price to ~$21.66/bottle:

The final price I paid for 6 bottles is $136.89 (including shipping to Sydney).

EDIT: Looks like it's back and still available today!
Can you confirm that it is?
