Firewire 800 to 400 cable Brand new

[HA_DA_JA]

Bought a new imac which does not have firewire 400 on it but firewire 800 on it instead.
When we were ordering my wife and I both ordered an 800 to 400 firewire cable so we ended up getting 2 and I only need 1.
I use the Firewire cable to connect my Pro Tools 002R via Firewire 400 to my new Firewire 800 imac.
Everything works as it should except now I have an extra cable.
These were $30 each.
SO I am selling a new in the packet shipped to anywhere in Australia for $17.
Cheers
