Okay I see, so I'd need another plausible item to send back. So I'd need something such as a much cheaper pair like £20 and say I got the wrong item and send back the cheap pair? Wouldn't they notice the order for 2 headphones when they look into my later orders? Or would they not look into it that deep.

Just so I'm aware that you're referring to my post, please quote me.

That's correct, you purchase a significantly cheaper Item that they stock, weighs around the same as the headphones and claim they've sent you that Item Instead of the headphones. Other orders on your account Is Immaterial- you can place a legit order for 20 headphones, It has no relevance to this particular one.

I am referring to your post yeah, okay so purchase the headphones I want and say I received a different set and quote the "wrong" headphones name. Then when they refund me and ask me to then to send it order a similar weighing pair that are cheaper.
I've found a pair weighing just over 50gs compared to the ones I'm ordering.
One problem is sometimes the courier is amazon themself, how do you stop them from checking themselves, say you called up the shipping first and they said I would have to contact support?
