In what seems to be an effort to carve itself a share of the fast food breakfast market, Subway is offering customers a free breakfast sandwich throughout the month of May. Getting that “free” food won’t be as easy as simply holding out your hand and saying “gimme,” however: you’ll either have to be the kind of person who likes to eat sub sandwiches before 9 a.m., or have a refrigerator to stash one until lunchtime, because the Subway deal is a buy-one-get-one situation: customers will get a six-inch savory breakfast sandwich “with the purchase of any of their favorite handcrafted subs” at participating locations.
