If the navy launched submarine sandwiches instead of submarines, their bready exteriors would get soggy and sailors would be covered in more olive oil than normal. Devour an edible ocean vessel with today’s Groupon: for $12, you get three foot-long sandwiches at Subway, valid at the 8145 Elk Grove Boulevard and Laguna Boulevard locations (up to a $24.75 value).

Ranked the No. 1 Submarine Sandwich Franchise in the 2011 Franchise 500 issue of Entrepreneur magazine, Subway has graced the globe with nutritious stacks of meat, crisp veggies, flavorful cheeses, and freshly baked breads since 1965. Three friends, relatives, or members of an understaffed barbershop quartet can wrap their paws around thick sandwiches such as the barbecue pulled pork, 12 inches of fresh-baked bread plumped to meaty perfection with 8 ounces of smoked tender pulled pork swathed in Sweet Baby Ray’s Barbecue Sauce. Italian-style meatballs bob in a bath of tangy marinara sauce, bringing a soft, meaty balance to the crunch of crisp veggies in a hot meatball-marinara sandwich, and comforting melted cheese wraps its gooey arms around juicy steak and tucks it into a hot philly cheesesteak. Lettuce, tomatoes, green bell peppers, and onions reminisce about the old days back in the garden, playing kick-the-cantaloupe in the foot-long, yeasty reunion hall of a veggie-delite sub, and white-meat turkey surrounded by its roughneck trio of ham, salami, and bologna picks flavorful fistfights with ornery vegetables, tackling them to the soft, bready floor of a cold-cut combo.

Though Subway sometimes features discounted prices online, this Groupon still offers the best deal available.
