If you’re looking for a free way to get a delicious sub, look no further than Subways’ convenient mobile app. Right now, you can take advantage of a tasty offer available through its mobile app that will get you a free footlong.
Place an order for two footlong subs through the Subway app and use the promo code FREEFOOTLONG to make one of them free. If Subway added that offer to its regular menu they could call it a Double Free Footlong.
