I def would include a receipt to play it safe but agree that it states PURCHASED between Nov 16th to Dec whenever.

If you placed an order for a preorder that just basicaly holds your place in line waiting for the device to be released.

You have not purchased it until they take money from you and shipped it out to you.

My question is are you required to send in the original receipt? If you do send in the original receipt what if you need to return your device will that cause any issues?
