- Conference participants usually like the opportunity to buy and sell such items as books, jewelry, buttons, bumper stickers, and various art objects. A sales bazaar is usually a popular place between programs.
- The conference facilitator needs to know whether the sponsoring organization has a policy limiting sales to items made by the participants, or, at least, to sales by participants.
- The conference facilitator needs also to confirm any policies on charges to vendors: flat fees for use of space or percentage of profits donated for specific purposes (such as scholarships for future events).
- Registration forms should include a check-off box for vendors and name of person to contact about fees and space availability.
