If you could go look at it i would pick it up in a heart beat. The 2 things i could only think of is it might be a newly hatched pied that has not eaten yet, in which case i would possible turn it down. Or it is his girlfriends snakes and he is selling them because of the bad break up, which could lead to legal issues. Go check it out, and tell us how you made out.
If you live near NY, and dont want it let me know ill go get it lol:gj:
