it use to be so easy...now its almost impossible....e bay has regessed in that area,..I need to do it also...sorry
What would be the purpose in ending an auction early?
one example would be you found a buyer out in the "real" world.
go to customer support...top right of screen...
click on polices..
it's in there...if You can't find it right off...type "end auction early" in search area...
I just did it...hope that helped
