I think it's just people who preordered, who just received them, or who know they will be getting their copies before the auction ends (and know there are workouts they don't want to keep, because they don't like certain types of workouts, like kickboxing, or step, or weights). I ordered all the HC's, but I'm pretty sure I'm NOT keeping IMAX3 or the Extreme DVD (though I won't know until I see them).
