I've noticed in the past that COMC user had a bunch of "SP" card of the Rookie Stars containing Ron Cey, Bernie Williams, and Ben Ogilvie. He currently has 174 of the 180 or so available on the site.

Doesn't really make any sense that he's pricing them all at $40 and they're all for sale. That means he's paying $1.74 a month just in storage fees at a penny a card. He could keep 5 for sale, the others in his inventory unpriced, and have the same chance to sell the cards.
