For a limited time, Subway is offering a new, in-app deal to customers. With the purchase of one fully priced footlong sub, you can then get 50% off the price of your second footlong purchase (of equal or lesser value).
To claim your 50% savings, you must place your order through the Subway app or website and enter the promo code BOGO50.
Like many Subway promotions, this deal does not include Wraps or the Footlong PRO.
