OCUK get away with a lot of stuff, Remember it's called ripoff Britain for a reason.
I once bought a supposed brand new Asus ROG 980 Ti Matrix Platinum, Not cheap, All the security seals of the box were cut open, Finger prints all over the backplate, Crap tons of dust on the fans and heat fin stack, I phoned them and they tried putting the blame on me, Sent it back and got a refund, I do not trust them as a company in general.
