Found this when surfing amazon's UK store. It might be a scam but its still worth a look if your desperate for one.
Did a reverse image search on some of their pictures of the phone an seems legit! Would like to wait for a few reviews first though.
Good thinking. Do you know anyone that has purchased an OnePlus One from uk's amazon yet?
