Make an offer. Something reasonably priced. I've searched completed listings on Ebay and it's sold in the past two weeks as low as $20, but the majority of the time, the only copies up there are the overpriced reseller copies.
I'm interested in $30 shipped, but PM me an offer and I may think about it if $30 isn't good enough.
Recently played this game multiplayer with some friends and loved the game. Want to own the Wii version since it runs in 480p and widescreen.
