Instructions:I got this gift card in the post from LOVEFiLM themselves, I have used it to re-activate my old account with 90-days free and successfully made a 2nd account using it to test it.
Enter code "XDMHCNEXQ".
PLUS £15.50 QuidCo for new customers who complete the trial!
I THINK it should work for everyone so please don't slam me if it doesn't =].
Edit: Confirmed working by several people, merry Xmas!
Edit 2: Any package can be used, 3 at once with or without games. Original link included with my letter is: http://www.lovefilm.com/giftcard if that helps.
Edit 3: Added QuidCo information.
Side note: I like way SOME PEOPLE copy my title changing a little (rollseyes) <_<
