Great site, my experience buying gold on runescape was the easiest I have ever had. I simply found a seller in the rs2007 section for selling gold, made sure they had vouches, and then PMd them. Got my gold in 5 minutes.
Prices are much cheaper than other websites - most sellers accept BTC and a few take paypal as well. Make sure to use a seller who is TRUSTED which means they have vouches. For trades over $250 you can also use a middleman on the site.
