I have had to send a couple items to ANOTHER UK company for repair - I was advised to value the item at "£15 - GIFT - old webcam" to avoid just this issue, with "the company"
offering a full replacement guarantee if something went awry like in your situation.
Risky, but in both cases no issue. Similarly, the purchases I have made diectly from them have been labelled as Old Webcam, NO VALUE
