Hi! I have an OBA account that I would like to start using over my current standard click and drop account. I have a few queries that someone that has used their OBA to send parcels might be able to answer, I have sent an email to Royal Mail but as expected the replies are slow currently. - Can the small parcels be included within the same bags as the large letters or do the small parcels need to be in their own seperate bag? - How do we pack the International letters/ parcels? From what we have read so far we need to seperate the EU and the rest of the world letters/ parcels but can the International tracked and signed and International signed be included within the same mail bag?
