From now through August 18th, when you purchase Guitar Hero II from Circuit City you'll get 1600 Microsoft points for free and free shipping on your online order. This offer is available online and in-store, but you'll have to send in a rebate form to get your money back. Check out the offer here.
True, we have seen a similar free 1600 Microsoft points offer before when GH II released and there was no forms to send in. But if you're willing to send in a rebate and wait for your cash this is definitely a good deal. Or you could just wait for Guitar Hero III or the game X3F is in love with ... Rock Band. Decide and plan your purchase accordingly.
