Going out on a limb on this one.
I had no idea what the Avengers were and why the deals got such high heat rating - I think I was living on Mars at the time!
Anyway, after watching the Avengers Assemble the heat kinda made sense but it was too late to buy the Bluray collection without paying £70+ until now...
Buy yourself the 7 disk bluray collection of Avengers, possibly a prequel to the Avengers Assemble - I don't know, I haven't watched them all and will spare you my reviews of the movies I've watched.
One snag - damaged boxing and possibly unsealed but disks guaranteed to be "unwatched and full working condition".
Anyway, despite being available for 2 years plus I can't find this collection cheaper than £50.
