I was thinking of doing the sealed box method but I want to keep the iPhone and the box sealed for reselling purposes. Do you think if I order and empty iPhone 13 box from EBay which costs about £10 and fill it up with the same weight as the brand new iPhone 13 and reseal it then return that back. Would that be a possibility and work?

If they scan the return (which Is very likely), It will not come up as part of their Inventory, hence they'll realize It's not their stock.

That's If the box comes with a barcode to begin with.

Would 20 g make Amazon suspicious?

Not at all, It's barely noticeable.

What method would you go with?

They're both equally effective, but as said, opt for the one you're comfortable and confident with.

I decided I’m going to do the wrong item method, I got a friend to order the Alexa to his address and I’ve ordered my IPhone to the locker. Both should arrive on Friday. Will keep you updated
