Count me in, especially to replace those damn Torx screws.
As far as mailing, I would take a toilet paper roll and cut it in three pieces. Take a section, tape one end, put the screws in, then tape the other end. Should be light enough to send with a 34 cent stamp, assuming you're only sending 10 screws or so. Otherwise use two stamps.
The envelope shouldn't rip open, but you may have to write "PLEASE HAND STAMP" on the envelope.
