just email them and tell them what you did. 
Mangaya people are pretty nice and im sure they 
will understand. I think lottery means that if 
more than one person orders the cel at the same 
time, they will hold a lottery. I know most of 
the time its first-come-first serve

hmm..is it just me or is mangaya a little over 
priced? I saw 3 cels that I have the same 
sequences of and I got mine for $100-$200 cheaper
