Circuit city is having a ton of games on sell this week. Probably the best deals are Resident Evil 4 and the Sega Collection for 10 bucks for PS2.
Even if you already own RE4, its probably worth picking up for PS2 because of its low cost. Its one of the greatest games of all time, and they added a ton of new content (included an entire new quest), and a progressive scan compatible widescreen mode.
