If you are attending a workshop, you'll need to assign your order with a Party ID#. This ID# is entered on the "Cart Page" before you are able to checkout. Each order can only have one Party ID# so if you are attending more than one workshop, a separate order must be placed for each workshop.
If you have been given a Non-Party ID# (NPO#) for your order, you'll enter that ID# here as well. Every order must include a Party ID# or NPO# before payment information is collected.
