Some have had problems with Beachbody - I did ordering HHA but was able to get it worked out a few days after ordering. I've never had an issue with QVC and they replace any of the product (I ordered Tae Bo from them once and the bands broke - they replaced them when Tae Bo wouldn't.) Course, if you use the replacement option with BB, they will also replace the workout which I had to do from the first set - my 20 Minute I think it was went on the blink after using it six or so months.
I would go with if you want another sculpting workout option to add to Turbo Sculpt.
Another thing to think about is if you order from Beachbody, you will more then likely be offered a special price for the other Turbo Jam packages. The Maximum series is my FAVORITE

as is Chalene's newest one Kick 'N Core. But that is only if you want to spend more money and I know that isn't always an option. I don't know how much you save by buying it at that time.
