It was always my assumption that the items barcodes are scanned and then assigned to your accounts order, therefore sending something you have bought from the same company would increase the chances of a failed claim?

If you send an Item from another company, It wouldn't come up on their Inventory when scanned, and the SE will definitely fail there and then.

The objective of purchasing from the same company, Is for the Item to be Identified as theirs. In terms of the orders on different accounts, If they decide to cross-check the details (many companies don't) It seemingly comes down to a mismatch administration error on their end. It's a similar principle to how a fake POP works- they obviously cannot locate It In their accounts/Invoice department, but It's assumably their administration error.
