Talk to Zapins about it; he should have some pretty quick. That's where I got mine from. He's generous with it.
I did find that it didn't ship well, recovering it seemed to be easier done using dry start rather than trying to re-plant it immersed. It grows fast once you've got it recovering; new shoots have just formed all over the place for me in the last couple of days while a good bit of the old growth melted.
