Tiki if you still want moss I have a 2 golfball portion of willow moss.
It has grown in the past 6 weeks that I've owned it so it is healthy.
It just doesn't work with my scape.
I paid $10 plus shipping for it, so it depends on how fast you want it. It fits in a small priority envelope. $5.50 I think.
