Please define "Additional Items" for me.

Can anybody please define "additional items" for me. Why do I have to pay additional shipping cost per item of the same sale? Before I understand additional items being items from other sales combined with this sale. And does this not fall under "hidden costs"? It is a single sale why do I have to pay multiple shipping charges?

This seems to be a no go zone for suppliers and Bid or Buy.  You are quite correct that there are hidden profits for suppliers in the "additional items".  My view is that this is not ethical as shipping cost should purely be the cost of using freight companies plus a small handling percentage.
