I think it is a great idea to post unexpected 
freebies. 

I was on the opposite end not to long ago. I 
received what I thought were two freebies from my 
deputy service in September 2002. I didn't think 
much of it. After all, one of the freebies was 
from a show that I had bought 4 cels (and 2 
batches of sketches)from the same seller. I 
assumed they were from him. It wasn't until last 
month that the deputy sent out an email asking 
everyone to check their freebies that I found out 
that the other cel was sent to me in error. I 
sent it back but I still feel kind of bad for 
keeping a cel that wasn't mine. :(
