Do you want a copy of Gran Turismo 5 before it's even in stores? Well tomorrow is your first chance at winning it.

Here's how it works:  Tomorrow (8/31), at some point between 11AM & 3PM EST @SubwayFreshBuzz will tweet a "Fire Drill" link, and the first 75 people who click on the link and enter their e-mail address will win a copy of Gran Turismo 5 for PS3, which will arrive before it's available to the general public in stores. The following Tuesday (9/7), followers of @SubwayFreshBuzz will have another chance to win GT5 where the Fire Drill prize will be 50 bundles of GT5, ModNation Racers, and Little Big Planet 2.

Customers can also win copies of the game (including the collector's edition) before they can buy it in stores by entering the main in-store promotion. Guests can find codes on specially marked 32 oz. drinks, bags of Monterey Jack & Sundried Tomato SunChips, and breakfast wrapper stickers, which they may then enter at Subway Fresh Buzz for a chance to win (you can see the full list of in-store contest prizes here). Codes will also be shared on Twitter and Facebook by Subway, PlayStation, and SunChips.

The Fiery Footlong Frenzy (which was created to support our two spicy new subs, the Turkey Jalapeno Melt and the Buffalo Chicken) runs through October 17, 2010.
