NOTE - Fee Limitation
This fee type can only charge by purchase location and not by payment type. Promoters who want to only charge by payment type (credit card only) can consider turning off the order processing fee in the box office and setting up a processing fee as a merchandise item that can manually be added to the cart when someone pays by credit card. Special box office fee items
