thats really crappy and I hope that everything gets better for the ones you have left and I would seriously report this guy if that is the kind of attitude he has. If they were all sick that is not a bad rat. I feel so sorry for you.
Yea, Its a shame when people do stuff like this for a Dollar.. But it Really sucks that the guy selling has NO CLUE what he is doing! How many snakes where sent out with this problem? How many snakes will die soon? Who cares! He made a Dollar!!
