Four more GGG winners are ready to master the store in part three of the Supermarket Masters Tournament. First, they must make a steakhouse dinner, even though the meat and seafood sections of the market are unexpectedly closed. Next, they must make an upscale lunch that is almost upended by the budget and restrictions dictated by the Food Pyramid. Then, the chefs create very different winner's dinners when one chef shops the odd aisles and the other the even aisles. Finally, for the first time in GGG history, Guy Fieri calls a fourth round, making the last chefs whip up their best breakfast in only 15 minutes.

The final four Supermarket Masters are ready to compete for the title of champion and the biggest shopping spree ever, worth up to $25,000. First, it's a dinner rush as the chefs get only 20 minutes to shop, cook and plate an Italian dish. Next, the chefs let a roll of the dice determine the components of their grilled seafood dinner. In the final round, the chefs have to shop for their ingredients for a "winner winner chicken dinner" using only a roasting pan, but that isn't even the biggest twist!
