Regarding wrong item received method could you give me an example of something that I could say? And surely they will ask me to return the 'wrong item'?

Thanks

In terms of the wrong Item, purchase a "stock" Item that weighs roughly the same as the SE Item, and Is significantly cheaper. Be sure to do It on a completely different account.

When they request the return, you'll send the wrong Item. They'll scan It, and see It's part of their Inventory, hence assume they've mistakenly sent that. A replacement/refund for the ordered Item will be Issued thereafter.
