Bought item with mistake

Hey, is it possible to refund a item back to gold? I just bought it 10min ago and it was the incorrect item.

from AH? No its not possible, only if u bought items from donation store.

Only items bought with coins from the shop can be refunded if report is made in 24 hours if you bought something ingame from the auction house you can try to resell it

And if you're lucky, you might even turn a profit!
