I'll use this thread to post video game deals for the week.
Kmart has a huge sale, lots of games half off!
Deals valid online and in-store 5/4-5/10 (both 360 and PS3 versions):
Final Fantasy XIII $29.99
Alien vs. Predator $29.99
Call of Duty: Modern Warfare 2 $29.99
Metro 2033 $29.99
That's a really great list. FF13 just came out last month and it's already heavily discounted. Bayonetta is a must buy if you don't have it.
