So if paired with wrong item received, FTID seems like a 100% success method. Because:

If the ftid gets sent to a different location its a win-win and you get your refund.

This is a win. And this...

If the ftid gets sent to the amazon warehouse you can say you received a different item beforehand, which weighs the same as the original item. Make sure you write this reason and the description of the wrong item when creating your returns label otherwise the warehouse will think you've returned an incorrect item.

...is also a win. You just claim that an other customer SE'ed this item before, and that he put the "junk item that weights the same" in there. My only concern is that the reps might ask why the shipping label looks "edited". I think then you just have to be creative.
