If you take offers on all your cels, you get to 
pick which offer works out best for you.  
Sometimes you'd be surprised at what you can get 
through an offer...even if you didn't consider 
selling it at first. Probably why its a popular 
way to sell nowadays...in just marking a price 
or taking offers on only a select few.

I still prefer ebay, and posting them at $9.99 
and see them go. Lately, Ive taken up offers too 
(only on my offer page), since quite a few of my 
titles tend to not be worth anything on ebay. 
But, never my entire gallery...
