Hey all

Urgent help needed. I am trying to book a reward first class on the sexy A380 from JFK to Seoul but am short about 15k miles/points on Skypass. I'm aware of the credit card which I will do if I need to but is there anywhere to buy miles? I saw this website but I am not feeling too confident - anyone ever used them:

Or any other places anyone has used? Your help is much appreciated!
