Once you sign up for a Piloto 151 membership, automatic payment is configured for the duration of that membership. You will receive an invoice at the beginning of the month, followed by a paid invoice receipt.
By submitting your first payment via credit card or other payment methods, you authorize Piloto 151 to charge your credit card on a recurring monthly basis for the membership that you sign up for, including recurrent monthly additional services.
