I placed a preorder for S23 from Samsung.com. An $800 bill credit promotion (via Verizon) for trading in an old phone is shown on Samsung.com. My question is how to start the trade-in and when I should start the trade-in process to get a total $800 bill credit. I heard I should begin the trade-in process after receiving and activating the new S23. If I go through the trade-in process right (I don't have the new phone yet), the estimated trade-in value is only $75. Can anyone comment on the trade-in process after purchasing from a third party like Best Buy or Samsung.com?
Thank you in advance for your help
