JB is right, OG UK just order it from the US, they have no control at all over the casting quality.
He is also right that the quality varies greatly. Saying all OG is shit is like saying all dogs are vicious. Some is dire and some (particularly the new 2nd edition stuff) is on a par with the best currently available. It is best to see it in person when possible and judge for yourself.
Disclaimer: I occasionally help them out at shows and have quite a bit of their better stuff (as well as some of the real dogs).
