If you accepted a trade-in offer but no longer want to sell your device, canceling is super easy — simply don't ship your device and your trade-in will be automatically canceled. There's nothing else you need to do. You will still receive email reminders to send in your device, which you can ignore.
What if I accepted multiple offers for the same device?
If you've created multiple trade-ins for the same device, ship your device using the shipping label corresponding with the offer you want. Each offer has a unique shipping label. Use the label associated with the offer you intend to keep and you're all set. The other offers will be canceled automatically after a few weeks and you can ignore any related reminders.
