Workshop pricing is dependent on several factors. Here is a partial list.
Number of people attending
Host churches receive reduced rates
Expenses (Participant Kits and Tools, Travel, Food & Lodging, etc.)
Number of Workshops and/or Clinics in the same location: TheMasterWorks takes out an insurance policy for each location where a workshop or clinic is presented. If several workshops are presented at the same location, there is a reduction in cost and therefore a reduction in price.
