I think only the chosen got an offer? I didn't get an email code and can't see it advertised anywhere. All I could find were Perks offers on Ozbargain but it appears not all Perks members got those codes:
$10 off with $50 spend.
$30 off with $300 spend, or $50 off with $500 spend.
PS: someone start the March thread, tee hee.
