Like the other post, it depends on if I like the 
cel or not. ^^; I've received several freebies in 
the past, and have sold most of them since most 
have been of characters I don't collect or 
specifically look for.  But I have kept 3 or 4 of 
them, one or two of which won't be very likely to 
leave simply because it's of a fairly rare 
character. :) I kind of felt guilty about selling 
them at first - but since they weren't something 
I bought, I figured why should I care? ^^;;
