Mine currently listed as UPS Ground in shipping - so we'll see.Apple trade-in boxes are delivered via UPS SurePost service. Don’t confuse it with the proper brown-truck UPS. UPS SurePost deliveries are handled by your local post office such as USPS.
What happens is that the real brown-truck UPS does indeed pick up your package but then hands it to USPS to complete delivery.
I’m with you. Mine was received last Thursday and they are still inspecting it. I just got done talking to them and they said the 3 business days is an estimate. I said it doesn’t say an estimated 3 business days! They informed me it’s taking longer due to the new releases.I have the tracking number. Says they recurved it according to Apple and that they are inspecting it
