Any shipping label that is generated through RDS eCommerce, including return labels through our customer return portals, will be counted as a shipment and charged accordingly. Only shipments that are subsequently cancelled, before the end of the week that they were generated (Sunday 23:59:59 GMT), will not be charged at the full shipping rate. Reprinting an already registered shipping label is not counted as an additional shipment, but re-shipping an order, including ‘Duplicate’ of an existing label (as in, generating a new label) is counted.
