As far as I know, this is the cheapest it's ever been.
Granted, by about 4p, but still.
At the very least, it's about £7 cheaper than anywhere else at the moment :)
I've not actually seen the second or third films, but the first is excellent, and I've heard the Blu-Ray version is a popular transfer.
The special features list was actually huge, so I decided not to include it in this description. If you're a fan of the trilogy, I'm sure it's a must have!
"Experience the Back To The Future Trilogy like never before for the first time on Blu-ray with over 2 hours of new bonus features.
