Wrong price?

[swi-1729]

What can I do to fix what I believe is a buyers mix-up.  A buyer offered me $11 and I responded with a counter offer of $12.  I believe he messed up because he bought it at the original price and NOT my lower counter offer of $12.  Is there anyway to "fix" the problem so that it sells for $12 and not the original higher price?

You can refund the difference. In your sold orders select send refund in the action menu next to that order.
