I'm curious how much this person is making their adoption fee, and if it's a firm fee for all the snakes, no matter the morph?
About your question, I have no clue if it's truly legally binding- but if you are really planning on breaching the contract anyway, might as well get a snake from a nice breeder and save yourself the trouble.
Yeah it's a 50$ fee across the board and it happens to be a clown. How they got it I have no idea.
