How much should I sell a second-hand iPhone 6 plus for?

There's not one scratch on the screen, no damage whatsoever, its in the colour gold, and it is only a year old.

Capacity? Expect $100 less than what the price of that particular model is now.

  • What should I know before buying a second hand iphone 4? So I've found a good deal for an iphone 4 but the thing I'm worried about obviously is getting scammed. I'm pretty sure it's not a China product but what I'm worried is things like if the iphone 4 is unlockable or not, the IMEI is blacklisted(do i have to worry about this too?). What other factors should I include when buying this? ** i'm actually going to see it for myself
  • Should I buy a second hand iPhone 4 with 32GB in less that 350$? Or maybe I should look for a 16GB iPhone 5C or somethin'? How major is the difference between them in a daily use?
  • Price of second hand iPhone 4S? I'm going to sell my iPhone 4S at the end of 2012 because I will need to study for medicine. Anyway, how much should I sell it for? I've had it from February 2012 and I've always been gentle with it. It has a screen protector and no bad scratches. Has never been dropped, broken or submerged in water. Australian dollar value please
  • Main things to check on an second hand iphone 4? I'm buying a second hand iphone 4 from someone locally and going to their house to collect. What are the main things I should look for so I know it's all working? Is there anything they are known for, for breaking? How can I tell if the phone is on contract? As its being sold as PAYG. Sorry if I sound like an idiot, I just don't want to miss anything!
