Alice Madness Returns + Mirror's Edge $10 @ Amazon

Here

They have a few other things on sale, but this seemed like the best deal to me.

There's also this pack for $15 that includes Burnout Paradise, Hot Pursuit, Shift, and Shift 2 which also is a good deal.

Wasn't a big fan of Alice, but mirrors edge is amazing, I loved the whole look and feel of it. Shame we never got a sequel :(
