I would would wager that the number of pledge signers who have refrained from dealing with Henry because of signing the pledge is less than can be counted on one hand.

If Henry went to an AC meeting with a Resorts 50¢ and offered it for $100, do you think he would find any takers. Let me put it this way, who on the pledge list at the AC meeting would not buy the chip from Henry?

It's easy not buy from a slab dealer if all that is offered is junk.
