Best Buy had the best deals that I saw (on the uber-dork version that I bought at least). I don't know if they're still cheap on the regular and limited versions.
come to Canada...I got mine for the trade 3 games get a free preorder at EB...and now Blockbuster has a trade 4 games and get the free preorder (but blockbuster usually has a higher TIV on games...so its pretty much the same deal)
Well BB has the preorder the game and get 1600 points for $5 or theres familyvideo.com that I think has it for $49.99 or the aforementioned lionsgames.com
