There have to be a dozen LFSs in Denver that have Java Moss. Not sure about prices there, but you can get a handful in Chattanooga for $5. Thus, going to an LFS and buying it will probably be cheaper than having it shipped.
"Jay223" and "chaberkern". I throw away a lot every week. Will cost about $4.00 shipping (probably a little less). Question is-- is it worth it for me to send you some. Not sure if your LFS has some or not, but it is cheap here. I usually donate some to my LFS.
