Sort of OT, but I was looking at the Trades board, and I noticed that several people were mentioning that they don't want codes from certain movies because you can only enter one code from each movie. Is that true? For example, say you did get codes from movie stores, like four from Pirates. Would you have to make four different accounts for that to work, or can it all be on one? I ask because my sister has codes that she's never going to use, but they're for the same movies that I own, Pirates, Rat, etc. TIA!
