The method involves carrying out a payment for a service provided to a user by printing a post-marking e.g. two dimensional bar code, in a destination address zone of a receipt e.g. reply card, delivered to the destination of the service, where the receipt carries a postage value equal to the money to be paid for the supply of the service. An independent claim is also included for a system for payment for a service provided to a user by a supplier.
