So a friend pointed out possibly the best bundle sale I've ever seen, the "Absolutely Great Square Pack" on Amazon.
This pack contains 7 games and 1 DLC at the incredibly low price of $10 (est £6.25).
What you get for this low price is:
Deus Ex: Human Revolution (Augmented Edition)
Deus Ex: Human Revolution - The Missing Link DLC
Hitman: Blood Money
Just Cause 2
Supreme Commander 2
The Last Remnant
