olivier,

if you look at the pricing on the rest of his 
cels, i.e. the sailormoon section, you will see 
that the pricing is not a fluke, this seller just 
likes to price things higher than the market. 
like I said, perhaps he just wants to sell a few 
for a good profit, or perhaps he bought them all 
for high prices. hard to tell, but in any case, 
you probably should not look at his site if the 
prices bother you.
