Just got an email now $180 off using referral link for new customers sign up.
$140 off first box
$20 off second box
$20 off third box
Keep on scrolling through referrals to find $180 off
(Note: While OP indicated this referral campaign will end on 1 February, we found the $180 referral links expire very quickly. For instance, OP's own $180 referral has expired in less than 6 hours.)
Hint for people trying to get a new user discount for the second time, use a burner phone number like the $0 Amaysim deal. Use a different name (make one up) and a burner credit card (or 1 time use credit card) like you can get for free from revolut. They caught me out with the same phone number (even though my number could have been reused by anyone) and charged me the rest of the full price value after it was delivered. I did a chargeback and got 100% back (I just wanted the difference), but it's a lot of hassle).
Hope this helps someone. Also does anyone know of any website that you can get an Aussie number for SMS for free or cheap for a very short time. I need to cut back on costs
