You are right.  I would not have been upset if it
was on their site for the same price.  But I did 
tell a friend about it and they did some research.

It IS the same cel.  And Nichibei is NOT selling
it for Hobby Shop K.  Nichibei bought it (at Expo 
in fact, or so I have been told) with the 
sole intent of putting it on ebay to make money 
off of what was a fair price by Hobby Shop K.

And no, I am not upset about "cels I cannot
afford".  Like I said before, I don't collect 
Gundam Wing, so I don't care how high the prices
are.  However, I am concerned about the morals 
the people I buy cels from.  While I know for the
work of bringing cels back from an exensive trip 
to Japan, there is a mark-up, I do not think that
turning a profit in the way I saw here is 
anything but greedy.  

Like I said, I am new to all this, so if this is 
the common practice, I just need to know that it
is the "way of the cel world".  I just don't want
to make the decision not to buy from a dealer 
whose morals appear to be lacking if they are
only following the standard.

Thank you all for reading, and thank you for the 
replies.
