When buying parcel postage from the Royal Mail website they give the option of bringing you the label as well so there is no need to print anything.  Simple delivery offers Royal Mail collection but what about the very important Royal Mail bring my label option - it is not available on SD.

Neither can you book a bring my label service when booking a RM collection service on their website.  It is only available when buying the label on the RM website. Simple delivery has taken away this option!
