This deal might be applicable for those people who are excluded from any more free trials with Love film i.e. they have already taken a free trial so are not allowed any more.
To get the 2 for 1 month I phoned up the customer services department and gave them the story "What kind of deal can you give me as as returning customer?". The lady on the other end of the phone told me the best she could do was 2 months for the price of 1.
The number I used to call customer services was 0844 482 0123 .
