I just emailed the guy....
"That poor snake Im amazed that its still alive. I know you said that youre unable to take care of it but wow... You do realize that its malnurished and dehydrated right? Snakes are not supposed to have wrinkles in them

you should lower your asking price so it can get a propper home and care asap."
I went on to say a few other things as well but will keep it off here.
My advice would be unless you have the space to quarantine, time, money and ability not to get too attached if things go even further south with this poor animal I wouldnt get involved.
