you want free gold then all you have to do is this.
1) buy a mount for 10 gold
2) lets say you bought a horse for the humans so put apost on LFG saying "cheap mount only 50 gold" now some 1 is going to fall for it because not every 1 knows that mounts are only 10 gold now.
3) it worked i made like 200 gold off this scam.
