Like *coughcoughAnimeCelBoxcoughcough*

People do it for profit, and business is 
business, but it doesn't change the fact that 
it's still crappy.  The small thing I can do is 
to simply not buy from and therefore financially 
support collectors and dealers that habitually 
outbid a bunch of people on an item to simply 
turn around and mark it up for more on ebay and 
on their personal sites *coughcoughagain*
