Usually I don't advocate using points to purchase goods (most offerings represent poor value), but I have just discovered a way to buy QC35s for just 33,333 AMEX MR points (works with all AMEX MR schemes). Given the narrow scope of this deal, I thought it best to post to the forums.
This may represent good value to people, as Qantas is currently selling these headphones for 72,500 points: https://store.qantas.com/Catalogue.a2?Page=ViewProduct&Produ…
Marriott is currently running a weekly 'flash' sale on merchandise redemptions with Marriott Points. The QC35s are slated to come up next week for 50,000 Marriott points: http://www.marriottrewardsflashsale.com/item/enjoy-your-favo…
Marriott and Starwood have now merged, which means that you can now transfer Starwood points to Marriott instantaneously.
In order to purchase the headphones, you'd simply need to transfer 33,333 MR points to 16,666 Starwood points (conversion rate of 1 MR point to 0.5 Starwood point for all AMEX MR schemes), and then instantly convert the Starwood points to 50,000 Marriott points (at a rate of 1 to 3).
You can currently pick up bonus AMEX MR points on a number of different cards (such as the AMEX Explorer, Platinum Edge and the range of David Jones cards). Full details in the wiki: https://www.ozbargain.com.au/node/275964
Hmmm tempting since I already have sufficient Marriot / SPG points.
