The 1st link is to the discussion of this deal [to help judge how trustworthy it is/isn't], the 2nd to the seller, who states that they can offer OEM licenses cheaper than usual because these are leftovers from system builders who now install win8 on everything. I didn't see anything about shipping outside the US, but they supposedly respond to e-mail inquiries promptly, so if interested, ask. :)
