Only if it is a friend I would be bidding 
against.  Obviously, a friendship is worth more 
than a cel, but normally friends have some kind 
of system worked out. I know a couple other 
people who I consider friends and have helped get 
Yahoo Japan IDs.  Basically, if we see each other 
in the bidders list, we stay away. But if it is a 
big lot, a lot of times we see if the other 
person wants to split it. 

For anyone else, I really don't care. If I want 
the cel, or anything else for that matter, I will 
bid on it.  I don't care if it is someone else's 
wishlist.  I don't even look at other people's 
wishlists anyways, so I wouldn't know if it was.  
I don't owe it to anyone else not to bid, and 
they certainly don't owe it to me.  I rarely ever 
buy cels and when I do, it is something I really 
want. I especially don't owe it to US bidders on 
Yahoo Japan who buy up a whole bunch of stuff and 
then sell it a month or two later in a "oops 
spent too much money" sale in which the cels are 
marked up considerably. I have no problem with 
importing to make money, just be honest about it.
