If you're Canadian and want to get some epic deals, now's a great time. They're currently offering free shipping on all used products, and are having a spring clearance sale where you can get up to 80% off on a lot of games over all the platforms. Note, some of these games aren't that great, but if you're a bargain hunter like me, you might find something!
I personally picked up Assassin's Creed 2 and Resident Evil 5 used for the 360 for $50. ;) Free shipping on used games ends May 31st! Hopefully some of you get some good deals! :D
