IMO there's no way someone would be ballsy enough to purchase a table at an expo and sell an animal in that condition to someone. Anyone who breeds ball pythons and sees that come out of the egg would cull the snake on the spot. Why would you risk your entire breeding reputation to sell a small normal? The value of the snake is under 75 dollars. It definitely looks like its neck is broken to me. If that's the product of mishandling a scared, new, delicate pet of yours then shame on you or whoever did it.

As stated, it doesn't matter at this point when or how the snake became that way. Euthanize it humanely. That's what the vet is going to do.

Source: I emailed my sister, who is a vet (albeit not a herp vet), to look at the pictures. She was quite upset about the idea of waiting another second to get that animal to a vet. If you're unwilling to find an emergency solution, the best course of action is to humanely euthanize it yourself.

Please do the snake the favor of asking some questions before attempting that, if that's the route you choose.
