...does everyone realize this can be applied to practically ANY type of show where things are bought and sold via booths? Man oh man ... in fact, a marketer could approach the organizers of some show or other and say "if I can raise sales to ___________(fill in blank on what might be appropriate for the particular show) - how about I get ____________(fill in blank with whatever your proposition is)" .... you leave the organizers a win-win situation ...if greater sales arent' generated (or more committement from sellers, etc.) - then they lose nothing.

Just an expansion on Don's idea that can work for everyone.
