My AppleCare+ email came in about 40min after the "Shipment is on the Way" e-mail. I got an Apple Email about "Trade-in kit" another 40 minutes after that.
I still haven't gotten an email about the Trade-in kit. Maybe I get to keep my iPhone 13 Pro? 😜
Mine showed up in the iPhone order, like once I clicked on it, I could see the kit
Trade In Kit usually ships after your device. So since Apple registers shipped today trade in kits should be shipping today and arriving over the next few days. You get 14 days to return it using the kit.
I could have sworn that in previous years the trade-in kit usually arrives before the phone, can't remember. But I actually just checked my order page now and I can see the the trade-in kit will arrive next week. Wasn't showing anything about the trade-in kit prior
