THEM: can i have the ball and the two books?  YOU: that won't work for me at all. the ball is important for me, and i'd need at least a few other items.  THEM: you can have all the hats, and maybe one book? so i can get the ball and one book  YOU: that only gets me to 5 and i can't make a deal for that low.  THEM: can i get the both books then?
