I picked up a new helmet at my LBS today saw a poster regarding this deal. Trade in an old helmet for 25% off the Giro MIPS range.
So for example:
I posted a deal a while ago and many people were surprised that a cycling helmet could cost up to $300. Anyway - with this deal you can pick up an Australian Standard AS/NZS 2063 helmet which is, by law, mandatory and required by insurance e.g. Cycling Australia (whether racing or not).
Interesting note is that I've noticed Australian helmets are heavier than overseas models (US/EU), with the European helmets being the lightest having owned all three versions of the Aeon.
Can you trade in any helment?
