I'm selling my Samsung Gear VR Headset. Reason being I've got a new one with my new phone. I used it when I got it in March but since then it's just sat there. I tested it today and it works fine.
Full disclosure this was part of a package deal with the S7 Edge which I purchased in the UAE. But there should be no reason why it wouldn't work with a UK phone.
Please check that your phone is compatible with the Gear VR
The price includes shipping. With a courier or Royal mail. Depends what works out better
