Just bought 5M OSRS GP. It's not much, BUT. I've sold to these guys many many times. They're the best.
I was also working with Travis when I bought my gold, one of the best customer service reps. I've ever encountered. Across any sales platform.
EDIT: I purchased gold VIA Bitcoins. Travis waited with me as my funds were being confirmed on the bitcoin network (anyone who trades BTC knows what I'm talking about). Once it was confirmed, he gave me the gold I purchased right away.
