Hi. I'm looking to purchase a Xmas present for my friend. I want to get the complete collection of films that have been released - LOTR and The Hobbit. I am not into these films hence why i'm here.

Can someone please recommend what DVD sets are available that contains everything plus a shit ton of extras. All the bells and whistles and i mean everything. I'm looking to spend no more than £100 to be honest but there's room for negotiation.

Can someone please advise what is the best thing to buy? I would really appreciate any help in this matter as LOTR is out of my comfort zone.
