I posted this in one of the other threads you started on this subject. (I guess if you start a thread, ask a question and don?t like the answer, just keep trying with a new thread?)
The official policy is that you can return online purchases an an Apple Store. Here's the [URL="https://www.apple.com/shop/help/returns_refund#mn_p]policy[/URL]. In this case, I don?t think the issue is the return, but rather it appears to be a matter of having stock on hand to handle the exchange. This is different from a warranty replacement where the stores have a dedicated supply of devices for warranty replacements.
I fully expect this to change back to what we have experienced as "normal" once the initial surge subsides, later in the year.
