Back in September, but I had to cancel my order and reorder it checking the option "Ship as items become available", as all of them aren't available. I guess some are on back order, sold out or just not released yet. I ended up placing my new order thru CD Universe (they only had 5 left in stock yesterday - found out from Videofitness.com) for the Maximize set and Cardio Kickbox. I will get the latter in a couple of days and Maximize at the end of Nov (or something like that). The ones I got from Amazon were released on 9/27 and I got them shortly thereafter (Shape Up FrontSide and Backside).
To the other person regarding "can she be as tough as Cathe?". I don't think they are that hard as they're only 1/2 hour, but I'll let you know after I do it combined with cardio and I have one day schedule to do them back to back. I'm not the best person to judge this, as I like variety and I'm pretty easy going with instructors I like or dislike.
