collecting chiped gems is a way to start, you collect all the chips, then flawed, and so on untill you have perfect gems. To SOME people 40 pgems can get a you hr. And that is a great accomplishment, untill you leave the game and it poofs lol. Ripping off a vendor is harder then ripping off a player. I dont know what you could program that could, 'hack' the vendor, other then finding a loophole somewhere where x item can be bought for xx and sold to y vendor for xxx.
