I orderered a case of the "Christmas Bonanza Premium Red Dozen" ($509 - 10% for PCP members) from Deidre in the Qantas Wine office in Sydney, and was advised that because of the triple points promo, she would only be able to offer a bonus of 3,000 points rather than the usual 5,000 (if I forewent the 10% discount).
So I opted to take the 10% discount and ended up with 28,131 points for $459, at a cost of 1.63 c/pt, which is probably the best available at the moment. The wine didn't look too bad either.
