2011 Giro Ionos for $133.19 USD + Postage

The helmet itself is actually 50% off from $235 to $119, but unfortunately postage is $37.99. Even so, it's still a pretty good deal for a brand new Giro Ionos. I'd check out the apparel on sale as well and it may ease the sting of the postage. http://www.competitivecyclist.com/sale/
Edit: Helmet doesn't meet Australian Standard Sticker on them and is technically illegal. You may have problems with the police or insurance company if that was to be found out. From a safety perspective though it will protect your noggin'.
Sorry, I completely forgot about the AS stickers.
