Expires 29th February 2012.
I did sign up for this (selected the highest monthly subscription :D) and quidco has been tracked already for £18. If you cancel before end of the trial period (30 days) you wont get charged. So you get one month free films (including online watching - if you select £13.50 a month package) and £18 pounds too. So basically you get £18 profit.
One new registration for a household but there wont be any problems of quidco tracking if u use a new email address...Hope this will be of help for someone.
