Once an item has sold how do I remove postage cost before buyer pays ?

[angelap3903]

One buyer has purchased 2 items from me so I wish to combine postage but they have already paid for one item and have asked me to remove the postage off the 2 nd item and send them a revised invoice.  How do I do this ?  I can’t find simple instructions on this site

Once they have paid you cannot send a revised invoice,   but you can make a partial refund for the difference paid this way:

You may need a PC/laptop and not the app or mobile browser to do this,  Chrome and Firefox work best with eBay.

If you are on My eBay Selling,  go right of the item sold and from More Actions select Refund this item.  Be careful to then add the correct amount of refund you wish to make,  or you will refund the whole amount.

If you are on the Seller Hub, click on the item in Orders >>  Posted and Awaiting your Feedback.   Then top left click on View Order details. Far right from More Actions Drop down menu,  you will see Refund this item. 

One tip,  before you send the partial refund,  mark the item as dispatched,  there is a quirk in eBay's programming if you send a partial refund first,  you then cannot mark as dispatched.
