Hi.  I don't see anyone ask or answer my questions in recent responses under this thread so I post on here in the hope to get updated information.

I want to post my items using Royal Mail myself on their website.  The reason is they have tick boxes to bring printed labels and collect my items for free.  That is simple postage for me, no queue for 40minutes at the PO or a drive to get there, simply note down the postcode on each item, done.  They drop the labels off and come back in 10minutes for the parcels, it works for me.

I am selling mostly plastic collector toys.  What do I have to do to enter royal mail postage with my own labels?  Is it change category?  Suggestions please?
