The marketing strategy of itshd.com is pretty aggressive, so be careful!
I didn't even complete the form, I just filled in my e-mail adress and then decided not to sign up after reading several warnings (including this page).
I closed the window without sending any information (to my knowledge) or clicking any buttons, and just a few seconds later I got an e-mail urging me to sign up,
Here is the e-mail:
"Dear Cinephile,
Our records show that you were unable to complete the signup process for a ItsHD Regular Membership. We would like to invite you to complete your registration and reassure you that there is NO COST associated with this offer, guaranteed. Complete the signup and watch a movie for free.
Signup for a FREE Regular Membership and Watch a Movie Now"
There has been a lot of reports about this site regarding problems with canceling subscriptions before and after the monthly payment kicks in, not finding the movie that lured you into signing up in the first place, a no-reply policy when it comes to questions and canceling subscriptions etc.
My advice is NOT to sign up and NOT giving them your credit card number.
