In the commercial with the boy claiming to be a Pokemon master, and asking for directions to a few older people who tell him where Burger King is, they start showing people trading toys for the special "Trading Night." One of the groups of children are two girls who trade the exact same toy!!!
If you think about it, kids do this all the time. They are really into trading things, even if it's the same item. And of course at times, they get really cheated as well. they are kids after all.
