Once I bought a last episode CCS cel and about 
two weeks later got another one 2 numbers off 
from mine in the mail . Though when I first 
recieved it, I was thought hey I already have 
this don't I? So I looked through my cels and 
sure enough I already had one turnsa out a seller 
had sent it to me by mistake, being a nice and 
gracious person I forwarded it on to who it 
belonged to. It's probably one of the strangest 
things that's happened to me.
