When I enter my coupon code at the end of my booking, the amount of the coupon is not deducted from the amount to be paid, why?

In fact, only the amount of the coupon will appear. But don't worry, the amount debited will be reduced by the amount of the coupon, as you will be able to check on the payment confirmation that you will receive once the payment has been made. If you still have any doubts, please do not hesitate to contact us.
