Nice score.......
Make sure you ask for a bubble mailer....I found this in his feedback.....
"Nice card, quick, but $8 for shipping 4 cards should include a padded mailer."
You should be walking away in cuffs! Those things rarely ever show - I remember when commons from that set would go easily at prices higher than that. I remember a Gretzky changing hands for $500 back when it came out.
