While I do like the system, I think either:
bidding by people being careless, or somebody's sweet grandpa trying to buy his grandson the game of his dreams before cancer finally takes him. The people selling the box remind me of the people that sold pictures of phones.
Or I know some people were selling their 'day one' achievement and live pass. But some people might want those. Can't imagine anyone really wanting to spend $400+ on a cardboard box.
I just don't get some people.
