Don't know if this has been posted but Deepdiscount.com has the Forza 4 limited edition for pre-orded for $69.99 with free shipping and no tax (not tax for me shipping to Alaska do not know about other states). Good deal considering all the stuff you get and also the lack of deals on Forza 4 and some places being sold out of the LE. If you don't want to enter in your credit card info you can use Pay Pal or Google checkout which is nice.
