widowmans idea is fine
except you don't even need to include the cd... cut down on shipping charges without it...
basically, buy a little bubblewrap (on the inside) manilla envelope the size for cds, put your cd's into labeled baggies, and postage, they're SAFE ADDY (make sure its to a place other than the grow site, like a PO BOX or a really good friends house that has nothing to do with the rest of anything) and a made up return address
drop into a us postal mail box
seeds arrive within 3-4 days
i know myself and others have never had a problem this way
i mean... i've heard others have never had a problem with this =]=]=p
