It would depend a lot on the quality of the 
information sold. If it's just to tell you that 
Mandarake and AWS sell some cels, that's pretty 
useless and a total rip of. Also, even if the 
information is good, showing a cel and saying that 
you can get "cels like that" with those 
information is misleading : chance are that you 
can't get a cel like the one show. (sell being 
unique...)

By the way, nobody noticed that there was a 
quantity of 5 to that auction ? Would have been 
weird for a cel...
