I always sell my boa babies at about 15% lower than the competition just to move them and not have to continue feeding. Im not going to quibble with someone over 20-30$ if it means I have to bring the animal home from the show and keep feeding it and take up rack space. Sometimes people phase out certain projects and just move onto something else.

That being said, I would be hesitant if I couldn't inspect the animal beforehand, and if there were heterozygous genetics involved and the animal wasn't papered. The majority of people in this business are fairly reputable at least to a basic degree. However, one instance I did receive a falsely labeled het pied who turned out to have a latent RI. Point is keep your wits about you and if the animal is healthy and what you want, go for it.
