how do I notify eBay that I have given a partial refund to a buyer

[daisy464]

One of my customers purchased 2 items and the automatic postage calculator for international buyers calculated her postage at $12.80 per item. This was a mistake. I have since changed the postage settings to offer free postage worldwide.

I refunded her the $12.80 for each item. Now, how do I tell eBay about it so I won't be charged final value fees on the higher amount but only on the reduced amount.?

You dont, ebay charge your fee on what the buyer pays, if the amount is altered after that, there isnt anything that can be done about it unfortunately. Ebays line is that you are supposed to 'educate' your buyers to wait for an invoice before they pay.
