I ended up sending John a letter with my contact information. He called me promptly once he received my letter. I ended up purchasing a few cards from him. It was a real pleasure talking to him. He certainly has a lot of knowledge about the hobby. Once we connected, he's been great to work with.
After being used to emails, scanned photos, and paypal for so many years, it was frustrating to have to send communication snail mail, but it worked in the end. Perhaps it's a lesson that everything in life doesn't have to fly by at light speed.....enjoy the hobby (at whatever pace) and the many different people and personalities that make up our card collecting world
