If you want something cool for free do the following:
1) take an envelope address it to yourself,
2) put some 1st class postage on it.
3) Then put that envelope in another envelope, and send THAT envelope to:
The Punk Patriot
PO Box 771
I'll put some cool stuff in the envelope you send me (the one with your address on it), and send it back to you.
This is how SASE's work. The last attempt to get this to work were not successful, because some people didn't seem to understand how mail works.
