Accidentally posted the wrong quantity

[jerm60]

I accidentally shipped the wrong quantity to a buyer and wish to send a second shipment. With eBay now controlling shipping, it's not obvious how I would do this. To complicate matters it was shipped via eBay's global shipping service. Any suggestions?

You could just send it off as you'll have to pay the postage yourself anyway.   Or you could list it at a nominal price for the buyer to buy again.
