A snakes value can also be calculated on what the breeder is doing project wise. Some breeders wouldn't pay $500 for a adult albino, as they are concentrating on projectswhich don't need albinos in them.(assuming you are not allowed to resell the animal!!) A breeder who hatches out several snakes of a certain type that he/she is attempting to prove out or needs for certain breeding projects will put a higher price on those snakes as they are worth more to that particular person.
I love pieds, and pay more for a pied snake than I would ever pay for a caramel albino for instance. I want cinnamon pastels for a project and will eventually pay through the nose for a pair. But I really need them for the project so I don' tmind paying the extra.
