* Group Registration offers approximately 25% off the cost of each registration for groups of three or more individuals from the same organization. At least three members of the group must be registered together initially to receive the group registration discount. Additional registrants (above the minimum of three) can be added during or at anytime after the initial group registration has been processed. NAMSS staff will be auditing group registration to ensure attendees are from the same organization. If you registered using a group discount that is not applicable to you, you will be re-registered at the prevailing appropriate rate and invoiced for the difference in cost.
