Susan S, which comes to the scary part of becoming exclusive, isn't it? How much say do you think you , as exclusives, have with the decisions of the site?
I don't think it is like that of a shareholder, but more like someone in the pecking order.  The higher your sales, the more preference you get, but unless you're a top draw, I can't see anyone getting the special treatment equal to that of being a shareholder.
