Long time stalker, first time poster. Let me know if I should make any changes to the post or if I need to clarify anything.
Got a message from Vodafone saying I could save ~$500 off an iPhone 12 and to call customer care on 1300 650 410. They confirmed that I could get $510 off any storage variant iPhone 12 on a plan over 24 or 36 months, and that it is not a targeted offer. Any customer (Vodafone or non Vodafone) can call Vodafone customer care and sign up to an iPhone 12 plan getting the $510 off.
I've posted a link to the Vodafone iPhone 12 page because I have to, but keep in mind the discount seems to only be available over the phone (1300 650 410).
