You can get avatar (legally) for free in DVD quality and watch it an unlimited number of times using the following steps:
1. create an account at blinkbox
2. "buy" a film (or use DSPYFIVE to get one which is under £5 for free)
3. on buying a film, note the link to invite a friend
4. find friend to give link to
5. get friend to create account (friend gets £5 credit)
6. get friend to buy avatar using code DSPYFIVE for free!
