We try to keep our margins as low as possible and earn on mass sales rather than on high-margin individual sales. There are chances that you paid cheaper than at operator's counter (we may have discount from the operator and use it in your favor). There might be an online booking fee that covers our expenses in case we do not get a discount from the operator. Train tickets are subject to manual handling and therefore require a higher fee. There is no extra fee for (almost all) ferry ticket bookings and the daytrips we offer.
