iTunes Digital Copy working 21st August 2013,
Amazon Verified Purchase(What is this?)
This review is from: Sex and the City: The Movie 2 (Blu-ray + DVD)  [Region Free] (Blu-ray)
Despite the digital copy code expiring in 2011, it seems to have been reinstated by iTunes, as it just worked for me, 21st August 2013.
Much kudos to the studio, and to iTunes, as it is now very rare to get proper digital copies with movies, unfortunately. Just those nasty UV ones.
Anyway, a massive bargain with a working code - to buy it direct from iTunes SD would be £7.99 today.
