Information for anyone who still don't know:
1) If we pre-order from Apple website and paid using CC, the warranty 1 year period start date begins on the date of the invoice. Same thing if you wait till 60th day to buy AC+, start date of AC+ begins on the date of the AC+ invoice. So basically you have "2 months additional" warranty on top of the additional 1 year that AC+ gives.
2) If we buy from retailers such as Harvey Norman, Challenger or iStudio, the set is not activated. AppleID not signed in. Turn on see display for dead pixel, switch off. Warranty does not start.
Bad thing is, don't have 14 days 1-1 return policy. Any scratches/dead pixel, once you leave shop after paying, they'll refer you to Apple shop. Apple will give you a new set with non matching s/n to your original box.
3) Buy on carousell from those who sign line off telcos. Usually if can wait, within 2 weeks, prices from these sources will be cheaper by $50-80. But then again, 50-80 is a negligible sum. If signed out from physical telco shop and they want you to activate, then wty has started. If its delivery to popstation, then wty shouldn't be activated.
