I think we're all bargain shoppers at heart - and whether we think a good deal starts at 10%, 25% or 43% off is irrelevant. A deal is a deal. And this week's Xbox Live Deal of the Week is one that should be worth everyone's Microsoft moon points.
Left 4 Dead 2's "The Passing" DLC is on sale for 43% off it's normal 560 price bringing it in at 320 . Calculating the current exchange rate, carrying the one, and taking out Major Nelson's commission - that'll set you back 4 real American dollars. That's a deal we can get behind for a DLC pack we were really impressed with.
