I have only seen 2 pairs of mated pairs on DD -- retired ones from ORA.
They have plenty of pairs there, but there is a big difference b/t that and a spawning pair.
Better off just getting a pair, and let natures take its course. First, how do you know you are getting a spawning pair? Unless there is a video/picture of that pair laying eggs, I wouldn't take anyone's word. Plus, shipping and moving into a new take can disrupt the spawning behavior. A while back I sold my spawning pink skunk pair to a local breeder, it took that pair 6 months to start back up.
