I've had it happen to me before. Someone else 
beats me to a cel I *really* wanted - only to 
turn around and immediately offer it to me for a 
trade.

Frankly, it pisses me off more than anything else 
and Ryouko is very right. . . I, and many other 
collectors out there *DO* keep track of cels from 
series we collect. We know what's sold recently 
and often, by talking amongst other collectors, 
we can even figure out to whom.

I wouldn't keep buying cels as trade bait. I 
would stop and think about how you would feel if 
someone turned around and did that to you.
