You first have to find a distributor. I think Wisconsin has one. Or you can order directly from the company if you can manage to get your foot in the door and can afford the minimum $1000 order, AND also have a loading dock available.
They are making it harder to buy privately, you other best bet is to buy from someone else that gets it in.
Otherwise, I do believe coldblooded.com sells it. You may even find it on kingsnake.
