After activating coupons and having now the first bookings I recognized that if a participant uses a coupon code (i.e. 15% off) the discount is given to the whole price - even if he / she bookes several places. Perhaps there is a possibility to set the discount to be used for only ONE place in ONE booking (i.e. to divide the discount by the booked places so the participant can book more than one place but he/she gets only the discount on one place).
thanks
