I am a seller and I mixed up two orders, one of which was Global Shipping

[treasuryhouse]

I mixed up two orders. One was worth  $120 more than the other. The buyer who bought the cheaper item let me know and started a return. The problem is the buyer for the second item is in China. I shipped to the drop spot for ebay international and it says my order was delivered. To top it off the buyers account is closed now. What are my options to try to fix this. Does the China buyer have any recourse to get the expensive item they ordered? Not sure how to handle this. Of course the honest buyer that is shipping the expensive item back has been refunded, not sure about the other buyer. I do feel terrible for them that they will be getting something that they did not order though.

If you’re using EIS to ship to your buyer in China eBay is going to eat the cost of that. Even if the buyer returns the item you won’t see it because once it’s delivered to the shipping hub, it belongs to eBay. 
You other buyer your going to have to refund. 
In the future be careful.

Buyer in US received expensive item, shipped it back and was refunded. Case closed.

Buyer in China is NARU which means eBay detected fraud. That buyer will not be filing any claims with their account shut down. Perhaps if they used a stolen CC the card owner will do a chargeback, but since this was delivered to the eIS hub eBay will cover any claims. Case closed.

You lucked out.

You will not get the lesser valued item back from the eIS hub for your US buyer to re-purchase. I'd offer the US buyer a discount off a future purchase for the inconvenience since this was a seller mess-up. Up to you if you want to do something similar @treasuryhouse .
