I really do not find anything to sell here. It's amazing how people try to find out business from everything.
People are easily fooled with cheesy marketing lines like - easy money and fast. Some of them will even pay for it as they think they will get a money making script/method to make them a millionaire.
Also this guy is selling through auto-buy links and over the past few years many scams have been conducted using auto-buy links. It is advised to stay away from auto-buy links even if someone is selling something other than gambling methods.
