Lucky for you—there's a very special buy one, get one free deal going on at the fast food chain. So, who's ready for lunch? Unfortunately, this deal will only last for a limited time. This offer is valid once a day through Aug. 6. When you buy one large sandwich, you'll get another large sandwich for free when you shop while the promo lasts.
