I believe that Melissa from Junkjungle said that 
she would bid for people for auctions in Yahoo 
Japan as long as they could pay for the shipping 
and the international money order. As she said, 
"Most sellers do not have a problem with me buying
stuff anymore since I have a decent rating.  :) 
I figure if anyone stiffs me on a cel I order 
for them I can always sell it to someone else
you likes it :)"
I'd email her first to see if she's still willing 
and find out more details.
