Ok, if you go to
http://www.cbs.com/bigbrother and at the bottom is a "subscribe now" button (
http://www.real.com/bigbrother/?pcode=cbs&cpath=web&rsrc=cbs_bb6_homepage)
You will have to provide a credit card to sign up for the free trial, and after the 3 days is up, you MUST call them to cancel the subscription. If you do not call and cancel, they will charge you $12.99/month.
You can also get the free trial and then pay $29.99 for all 3 months, however, after the 3 months is up, you must call again to cancel the subscription, or they will once again charge you for another 3 months of NOTHING.
Hopefully, this will help. Post any questions here!!!!
