yeah, those last two are the really expensive ones...the ones that have their newest edition out this year.
EDIT: I also haven't ever wanted to use an older edition than I was asked to. I know sometimes one edition to the next simply changes the wording of one sentence or something, but I was given an older edition book for my psy101 class and the chapters were out of order and stuff and it was a little difficult to keep up.
