Michael,
I had a grump at Kogan / Dick Smith via email when I wound up on what I assume

Update:
After a brief respite (or maybe they didn't send anything out) kogan.com
/ dicksmith.co.nz are right back in to spamming.
I did note their latest email did not hit the Return Path rule, so I
don't know what the status is there.
