I did a search for P90x products over a year ago and found that they are not easily sourced through wholesale. You may refer to this post:

I ran another search today and still end up with the same conclusion. I almost fell for this site, wholesale-p90x.com until I checked their registry info and found that they are actually a Chinese company based in Guangzhou, China.
As for Zumba, they offer wholesale program for shoppers who sign up for their ZIN membership. To learn how to become a ZIN member please go to this link: Link hidden: Login to view
Irene will do a search for Daria series suppliers for you.
Hope this makes a warm welcome! =)
