You know all of this just because the guy is selling his snake for cheaper than the average price? Maybe he doesn't have a good reputation yet or a lot of positive feedback, but everyone has to start somewhere. Until he gets feedback saying he is reputable or not it isn't fair to jump to conclusions and condemn him. Why aren't you tearing into the OP for trying to buy a snake that is young and hasn't eaten? Consumers have a responsibility to educate themselves about the item they are buying just as much as the seller has to be honest and open with the buyer about the item.
To me, YOU are the perfect example of the bad side of this hobby. Making snap judgments with little to no real information about the situation at hand. Did he ever sell you a sick snake? Do you know anyone he ripped off? Didn't think so. It's horrible to try to ruin someones reputation without any real evidence.
