"If you really want the cel you won't mind a
little competition?"

That sounds like the words of someone who either
doesn't value money or just likes to see the
cel market inflated...

Posting a URL to a cel gives the cel more 
attention.  This is good for the seller, but
bad for the bidders.

Are you saying this hobby is only for the rich?
I completely disagree... yes, obviously the people
who make cel collecting a hobby must have some
spare funds (that aren't spend on food, shelter,
etc) but to be forced to spend 3 or 4 times
the normal market price on a cel (meaning what
the cel would've gone for if someone hadn't 
alerted everyone - even people who weren't
initially interested in the series - to visit
the link) because a poster on the forum created
a feeding frenzy... well, you can stick that idea
in your ear.

And to reply to the above post about making the
seller happy:  Did the seller post that link?
If so, why remain anonymous?  If not, whose
business is it to drive up the price in order to
please the seller?

Sometimes I wonder if you people who think
"freedom of speech" answers everything actually
consider both sides of the story...
