Vouch for YoHoJo. I've been doing business with him for years. I took a long hiatus from Sythe/OSRS, and immediately upon returning he gave me the same great service. My most recent transaction with him was a quick, easy, and efficient trade of my BTC for his Tribot credits. I went first, and he came through immediately.
Always a pleasure doing business with you, YoHoJo.
