Strange this is the second time something like 
this has happened to me.  
Last year a cel I bought at Taro was copied by 
someone and they were selling  the fake on ebay 
(I bought it so I could destroy it) and now 
a cel I bought on ebay is being illegally sold 
on Yahoo by someone who does not own it.
You have to be careful I guess and only buy from 
trusted sources and people with good feedback.
