Is it possible to set up a price set such that selecting multiple options would lower the total price?
Our use case is a summer camp. You can register for a day ($50) or for a week ($190). We need to be able to set a maximum number of participants for each day. So, if we could make a form where you simply select all days in the week to register for an entire week and a $60 discount was applied in that case, this would satisfy our requirements.
Putting in the week as a separate option would make it impossible to have registration limits for each day. The camp has multiple weeks over the summer, so we can't use a registration limit for the whole event to do this.
This is currently set up as a webform, but that comes with other issues, so it would be preferable to find an option that works with price sets and CiviEvent.
