I voted for "individuals," but actually I only ordered one--the Stretch Max dvd.
I don't have any stretching videos, and it's really the only one I want. To take advantage of the free shipping, I'm getting the Step Blast/Step, Jump and Pump dvd....I've been wanting this one for a while.
I debated about getting the whole series because currently, my Cathe collection is small, and I have been working out exclusively with Cathe since February. I have the Intensity series (which I love) and a few Body Blasts, and I am not bored with these yet...maybe because of the variety (premixes, etc.).
I may purchase more of the Hardcore series after they are released, depending on reviews/opinions/recommendations.
