I just went through the complete process of an Apple Trade-In for the return of my “old” 13-inch MacBook Air after getting my brand new 15-inch MacBook Air. I’m super impressed by the logistics behind all of it and how the user (me) is guided in the process. The final step was to cancel the AppleCare+ that I originally bought with my old device. Took a 5 min call from somewhere in Texas. The call was automatically initiated from a web form I filled out by selecting a few options. Got a confirmation email before the call and after stating the actual amount of the refund. All done. Great user experience. The next time will be for the replacement of my iPhone 13 Pro with the upcoming iPhone 15 Pro. 😃
