I want to buy multiple items from the same seller but by making offers on them .
As far as I know you have make offer and if accepted pay straight away to procure it.
How do I go about making multiple offers and getting them with combined shipping ?
Thanks.

Can you message the seller and see if they can advise?

Yes
I could make a list and send it to the seller and ask for a price .
I will try that never really thought of that and see what happens .
Thanks
