As a vendor, how do I change my event item stock or turn an item off?

Under Items at this location you can change the quantity you bring per day (0 to 10,000) or turn an item off or on, without a new review. You cannot lower the daily quantity below what customers have already reserved. Price changes are not possible this way; prices can only change when you edit and resubmit a registration after the organiser requests changes. An event price of RM 0 makes the item a free reservation. Customers see an item as sold out for a date once that day's quantity is reserved.
