Just saw this in the Hoyts website, which mention this for limited time only.
Hoyts is celebrating 100 years by offering a book of 10 adult tickets for $100 + shipping express $7.50. That's $10.75 per ticket!
With the current adult ticket priced at about $15, I think this is quite a worthwhile savings especially with movies coming out soon such as Transformers 2, Ice Age 3, and Harry Potter. :)
Worth noting, from the Hoyts website:
Super Saver vouchers are valid for any session except on Saturday after 5pm and are valid for 6 months from the date of purchase.
