Hey gang, (KL and S.gent) thx for the info on canary....super prices! and he sure seems solid with trust! Now if i can just figure out how to send and sign etc,,,lol, but its all there I just need to study his thread again, can't be that hard 
It's a little odd at first. Depends on which wallet you are using: client or blockchain.info
I use blockchain for my payments. On blockchain you send your payment first. Then click the "receive money" tab. Click on "actions" and select "sign message".
Enter your name and shipping address in the box, and click "sign message". You will get a signature string. Copy it and close the box. Then PM Canary in the format he has requested with your wallet address at the top, the shipping address you "signed" with next, and the signature string at the bottom.
