You need to activate a discount coupon in the booking details before making the payment. You can do this either right after sending the request to the sitter or after the booking is accepted. Simply click the "Apply Coupon" button. The specific percentage discount will then be applied. The sitter will also see the applied discount on their side. Once the payment is made, it will not be possible to use another coupon for that booking, nor can the same coupon be used for another booking.
