For many, the stores are closed where they live. Thanks for the post, though.I’ve had to deal with this. Here’s how you get around it.
You HAVE to go to retail store. Make sure the store you go to has the right size/band in stock otherwise you’ll waste a lot of time for no reason.
Tell the Apple Employee to process a “No receipt return” and process it as an exchange to the band you want.
They will need a manager override but as long as you don’t have a difficult employee/manager, it will be done.
I think Apple will modify their policy very soon.
