Have been wanting to see this series and found this the cheapest price anywhere for the Blu Ray version, and with free delivery. Obviously this sort of title won't appeal to everybody but thought I'd post this for those that it may.
Price comparison wise, it's over $10 cheaper than JB who currently have it at $27.98 and Big W $24.82 (plus $4 delivery as I doubt physical stores would even stock this title).
It does not even have a release date until April 2014 in the UK, so unfortunately Amazon, Zavvi and The Hut are out.
There's only 3 episodes, I found them interesting but nothing new or spectacular.
Sherlock is a good narrator.
