We need the coupon feature to work with a limited amount per user. For example, instead of being able to discount $XX per registration, we want it to only allow each constituent (per email) to receive the $XX discount.
I agree. We're finding that having a discount per session is useful for Early Bird discount pricing on each session. But there are also times when we just want to do, for instance, a one-time $25 off your entire transaction. It would be nice to have the choice on how to apply the coupon code.
