I found a copy of this at my local Hastings for $9.99 last week. It was in a bin with other new games for $9.99. You guys might want to try there if there's one nearby.
I picked up two tonight and the clerk let me trade one of the Tekken 5s in towards the purchase which saved me about 7 bucks. I thought that was pretty nice.
If I remember correctly this is the same game as Mashed which came out a couple of years ago in the UK. I played the heck out of the XBOX version. It's crazy fun multiplayer especially whiskey-assisted! If it's the same game its a steal at $10.
