You could always make a sale page.  There are 
plenty of good free services - 
http://www.freewebs.com or 
http://www.weebly.com/  for example.

There you could show the cel & the price you 
want for it or just show the cel & ask for 
offers.  These sites are really easy to use with 
no html needed.

If you have any Fushigi Yuughi, Inuyasha, Card 
Captor Sakura, Vampire Princess Miyu, Sailor 
Moon, Dragon Ball Z, Ayahsi no Ceres, Shamanic 
Pricess or Kenshin (you know the series just 
about everyone else collects, lol.); I'd be 
interested.

Good Luck
