Theres no mention of it on their site so it may be one store only but at my local store (VIC) they had this nuts $10 sale.
I picked up 2 hoodies for $10 each. One was a "New York" print which was quite heavy and warm, absolute bargain. Usually $29.95. I could'nt find the same ones listed on the site, but I did see these ones:

They also had two kinds of jeans for $10 (they were regular fit, I like loose so I did'nt buy) and long sleeve jumpers for $10.
We also picked up two iPad 2/3 slip on covers for $2 each!

So if your nearby it may be worth checking out!
While trying to find the sale info on their site, I also noticed they have lots of BABY clothes marked down to $5 on their online store, very cheap. http://shop.cottonon.com/shop/kids/sale/
