I can only speak for Florida...

That said... here you must get a license to sell Class III exotics in order to sell BPs(and many other exotics). So if I were to sell BPs online to people without this, that would be a illegal online sale. If there are local laws prohibiting sales/breeding/owning the animals, those sales may also be illegal online sales.

If the snakes were indeed in need of rescue, I hope they are in a better place.
