I was at HMV Oxford Street yesterday and saw this for £8. They had quite a few, but I'm not sure if it's a national deal or store specific. I also got an additional 20% by being an O2 customer. It's worth checking your local HMV for. Can't go wrong at this price for all 3 films on BD.
The set is currently £21.75 on Amazon
Spanning ten years, likened to The Godfather trilogy, this is the gangster epic of our time. Presented here for the first time on UK Blu-ray in its entirety, this is Infernal Affairs as it was meant to be seen.
Ming and Yan live parallel lives; one is undercover in the Triads for the Police, the other is a mole in the police. Eventually their paths must cross…
Infernal Affairs 2
We go back ten years to see their lives as they first were when they were initially recruited into their respective roles. Friendships fracture, foes join forces and nothing is as it seams.
Infernal Affairs 3
10 months after the first film we see Ming as he attempts to fit into the police force and slowly morphing into Yan as he has to come to terms with the life he has chosen.
