Trade In

If you elect to use Apple’s online trade-in option, you will initially pay the full price for your device.

If the trade-in is returned as instructed, after being been inspected and accepted for trade-in, you will receive a refund of the trade-in value to the Credit Card used to purchase the new device.

However, if you fail to return the device for trade-in, or the device is rejected, nothing happens; you’ll not receive a refund. That’s it - the end!

I am not sure what you are asking and why are you asking?

Never mind.

I have no clue what you are trying to do/accomplish by asking this.
