Contacting card owners in TPG registry.
 

I've tried to contact some of the card owners at PSA that have cards in their set registry with contact information that I'm trying to purchase. How can you get contact information through SGC or any other than PSA that may have a registry? It's worth a shot. So far no luck, but I don't like to leave stones unturned if I can turn them. Any advice would be greatly appreciated.

What has worked for me is to see what they need to improve their registry and trade for what would improve my collection. Outright purchasing doesn't work unless you can improve their registry numbers, after all that's why they're there. As far as reaching someone there with no contact info might be tough, some of them may be members here though.
