I am hoping to use the Event Items functionality to offer event attendees a no-cost choice for an event. In testing this, it seems that if there is only a $0 event item in the cart, it’s not possible to checkout whether or not there is money in the scout account.
What I would expect is that you would be able to checkout. If some sort of payment method is required, then allow scout account checkout if the cart is $0, even if there is no money in the scout account.
