Walmart.com / Best Buy is doing it without codes but if you prefer Amazon here you go.

I myself paid full price $499 on release day of this bundle and I am very disapointed.. they need to make a offical price drop already and quit causing other people problems..this has only been out 10 days.. If you did purchase via Amazon for full price you can get $50 credited back to you via Live Chat.. it took about 30 mins for me but I did get the credit back.. this also works on the normal bundle with Forza if you are not interested in TitanFall.

Enjoy!

I can't imagine the disappointment of people who got the standard version a month or so ago before this bundle was announced :(
