Not sure if this is targeted; I received this code via email after leaving the sign up page on WoodYouLikeSomeCash's deal.
It's Only useful if you port in from Telstra or Voda.
From the Email:
Use BUHBYE to get 100GB for $28/mth if you transfer your number over from Telstra or Vodafone.
Hurry! This amazing offer is ending on 1 March 2020 00:00 AEDT.
T&Cs apply. 100GB plan reverts to 20GB for $28/mth after 12 months. All for use in AU; resets monthly. Excess data: $0.01/MB.
Not applicable to me as I was transferring from Optus anyway.
I just left them after 3 months. Unless you need the 100GB, i've go elsewhere.
