Awesome deal! I love this game! Very original and a lot of fun. If you're on the Overstock mailing list, they sent out a free shipping coupon last week. It's one-time use only through the e-mail link, so there's no code.
Overstock is notorious for cancelling orders though. Had two of mine cancelled before and only one ever got shipped, which was Spikeout (Xbox) when they had it and no one else did.
I got Trauma Center a few weeks ago at TRU and it's definitely worth it. It's funny that my girlfriend watches surgery shows with no problem, but got grossed out by the video game cartoonish surgery! *lol*
