I was just looking at this plant so you are in luck, lol...
I was looking on Amazon.com, and found two people who are currently selling them. There might be more. My suggestion would be to get the name of the people selling them and then do a google search for the actual companies and buy directly from them as opposed to through Amazon. It might be cheaper that way.
I know one of the companies was Carter & Holmes, but can't remember who the other was.
