Was on sale for $10 a week or two ago (http://www.ozbargain.com.au/node/47142), it's now even cheaper at $4.99 for the game plus required $15 for a month subscription. It's also $9.99 for the collectors edition.

I believe you have to make a trial account first and then upgrade, I'd recommend doing that and giving the game a go, especially given this deal is for a week, unlike the last which was a day and a half.
My referral link thing, not entirely sure it gets me anything I want, but from what I can see it doesn't disadvantage anyone at all:

When you Ascend a friend, you will both gain the following benefits:
You and your friends will be able to summon one another once every 30 minutes.
Your Ascended friends’ characters will be automatically added to your Friends List, and your characters will be added to theirs.
Your Ascended friends will earn the in-game title, “The Chosen.”
How much is the game normally?
