Hi. I am so stuck! I sell children’s clothes. I buy clothes from people all over the country. I send them a bag with a prepaid postage label on it. The problem I am finding is that some people are ordering them and not using them. I have then obviously forked out for the postage (which is quite a lot for a medium parcel!) and then not used. Does anyone know of any companies that don’t charge until the parcel is dropped off? Thank you for reading xxx
