What Tim means by how many people need to be paid is that in order for me to sell you a pen at this venue there are many people that need to be paid, the first person is the purchasing agent who buys all my equipment and supplies, then the artist that makes these, then the book keeper who makes sure the bills are paid and lets me know if I can make a profit, then the show manager who sets at the desk and applies to the shows and has the book keeper pay the jury fees, lets not forget the guy that packed all this in his van and drove 10 hours to get here, oh did I tell you about paying the guy who spent the day before the show setting up this display, and the salesman who sells you this pen , so if I give you a 30% discount 3 of these people won't get paid, do you think that's fair but here's what I will do I'll give you a free refill now and the next time I'm here another free refill.
